124" build...I'll let the cat out of the bag

[No Cents]

    just to set the record straight. I e-mailed Fred last night and asked him about this annealing process he has mention to me numerous times.
His response was:
the heads are already annealed and the crack was welded up...and the heads were then sent out for a heat treating process.

I hope this clears the air up. Apparently I misunderstood him on the process that the heads are going thru.
Sorry for an confusion from my end.

After having a serious amount of welding done to my heads by Fred to get 400+cfm out a 2.180 valve they were sent off for the same process. Problems would arise by having soft spots around the head due to the welding. Poor head gasket sealing issues and pulled threads are possible by ignoring the re-hardening process.

  as far as the annealing process goes...
the heads on this 190hp Hemi Engineering bike were done by Fred...and the heads on it were annealed.

  I'm confused with your 
what are you scratching your head for there Rich Kid?

Ray

.  I was confused with the whole head issue,hopefully you'll get it together and make more power 

[pwmorris]

  I just bolt it together.
I leave the specialty work like the heads to the experts...because I don't have the knowledge they do in their field of expertise.
  All's I can do is choose certain people to work their magic and place my trust in them.
I'm trusting in Fred that he knows what he's doing. He has worked on the heads for some serious big horsepower builds in his days.
I don't think his goal is to see my bike go backwards in the horsepower department...and mine either.

Ray

Smart-
Your heads will be fine, and if there was any issue making them good as new, or even better now, your head guy would have told you.
Have you decided if this is going to be a hot street bike, that can still do daily riding on pump, and maybe have some fun at the track once in a while,
Or are you focusing building a race bagger now?

[No Cents]

  Paul...I'm not bumping the compression up any so I guess we'll call it a rideable street build for now.
Fred did say the heads will be returned flowing more than they did before. 
This build has never been right...so I got my fingers crossed this time.

Poor head gasket seal is one I have seen often. When intake ports are welded on, after time the head gasket surface directly below the port will move around. I have also seen the valve seats beat into the head because of the lack of heat treat after welding.

  after having a few long conversations with Fred...we came to the conclusion to pull the CR651's and I put the S&S 635HO's in today for the 1st time.
  Fred is setting the heads up for them with their larger .284" exhaust TDC lift. So the compression will be backed down a little to the 11.2- 11.3 ball park depending on the final cc's of the heads. The heads will be un-shrouded and a bigger intake valve will be installed. We both think this will be an angry combo.
  With running these 635HO's I will be lowering my static compression...but with these cams my corrected compression will be higher than before. I'm still going to run 1.725 stilts on the intakes.
I personally can't wait to see how the 635HO's perform. I've been wanting to try them for a long time...I just never had the needed clearance for them.

I concur, party on man! 

[06roadglide]

I'm stoked that you're going with the 635's now.  I think you're gonna see the best out you're build with that cam.

[No Cents]

  I hope so.
Fred seems to think the whole dyno curve should move to the left and it should show much higher numbers a lot sooner in the graph. The 635HO's seem to historically carry the torque curve out across the board rather flat after that initial burst from two grand. Fred thinks it will show an increase every where over the 640's that I had in it prior...especially with the bigger intake valves he is sticking in the heads. He says it should make more power than before...even with the drop in compression.  I guess time will tell.

Has anyone run this set up in one of those Computer programs to see what it comes up with,or is this off the Charts for that to be done?

It would be instresting to see both cam's back to back once the heads are completed... 
I know Ray it's just more money......... 

[wfolarry]

I think the 635's would work better at the track if you ever decide to take it for a trip down the 1320.

  this up coming spring (God willing) it will be doing just that Larry! 
I can't wait.
I shouldn't say this...but my goal next year is to get a 10 second patch...and before the end of the season maybe make enough improvements to get a 9 second patch. It's always nice to dream.

[HD/Wrench]

The testing is always great but I can tell you first hand that even for me its a issue many times. The amount of time that is taken up for testing is huge, not to mention parts cost. I had 637 pulls ?? or very close to that on my 2009 SG. That was all testing from a 96 to 103 then 107 cams, ex t/b heads etc .. Some of that I was paid to do and some I was not..


Ray the copper top  can get into the 9 area I  say go for it . 

[IronMike113]

Ray I'm going to start a  Christmas tree light Fund for you ......... 

You get it Christmas Tree.........  Practice practice practice ..........

[No Cents]

  I hear ya Mike!   

thanks also Steve! 
It's been my goal for a couple of years now to get this thing strip ready enough so I can have some fun with it...and not totally embarrass myself.
  This thing has given me headaches and heartbreaks along the way. It seemed when I felt like I was getting close...one problem was just followed by the next. I hope with this last recent tear down and freshening up...it might meet the expectations of what I'm after for a street/strip ridden bike. If it turns out to be good and solid after the tune...it's just waiting for spring to roll around so I can start doing the 1320's.
  My list of things to do to the bike is growing shorter and shorter. I still would like to get a Pingel electric shifter and a shift light...but that won't be stopping me from going racin. I will be getting the Zipper's Performance axle and chain adjusters after Christmas is over to replace the factory's stock cam axle to see if that takes the problem away that I'm still having with my chain losing tension after I hammer hard on it.
  I think this is going to be a long winter for me because I know I'm close to finally seeing my goal happen.

I wood like to see ya set your sight higher than a patch or tee shirt.

  baby steps for me Jim...I can't set my goals too high when I'm just getting my feet wet next year.
But I'll be giving it all I can.

      Ray have you ever considers one of those aluminum swing arms? Ive seen photos on this site I think from BVDBOB and they look pretty sweet. Will the Zippers axle allow the use with a 30 tooth trans sprocket with the stock belt?

[No Cents]

 Patrick...if I want to run this bike in the AMRA bagger class I have to keep the stock swing arm. I have looked at the after market swing arms out there...and there are some very nice ones to be had.
The Zipper's axle and adjusters is for a chain drive set up...but I don't see why it couldn't work with a belt.

I was talking with John at Zippers a week ago,  they are developing one for belts now.

@ the end of the day this is a Bagger     i enjoy the endless effort you have put forth with this bike. The post and the read    you have switched head porters and  have basically turned everything in another direction for this bike 

best of luck Ray! what are you after N/A
