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

[No Cents]

  Eric...from what Fred told me this crack went from under the seat all the way to the spark plug hole.
I'm sure it had a major affect on it.
Fred said he welded it all up and he will drill and tap for a new spark plug hole when the heads come back from the annealing process.

My concern would be how far or deep the crack went.
Did it crack through to the spring seat area, into a port? Hard to say without seeing it yourself.
I hope it all works out for ya Ray. It sucks that it happened but if you're like me, it makes me feel good when I find a problem.

[No Cents]

 mine too...but Fred assured me he has it handled.
At this point all I can do is hope for the best.

It happened a lot on the Evo's. I welded enough of them that I don't think you'll have any problems with yours. I never annealed them so you're one up on me there.

I had some heads annealed once. The head porter advised against it, thought it would be expensive, would distort the heads, etc. At the time I was pretty deep into a set of rare castings and couldn't really afford to flush the castings or all the work that had been done to them. It took a considerable amount of welding to fix them. Enough that the porter was worried about changing the temper of the heads. I went ahead and had them welded and then sent out to be rehardened back to T6. After that the seats and guides were way off from each other. The porter fixed them. In hind site, had the castings not been so rare (STD spread valve, oval port, BT) and had Baisley not already done so much work to them, I probably would have walked away from them and started over.

Evos crack there all the time. Just what happens when the hole is close to the seat ring. Pressure from the press fit and lack of support contribute. Annealing happens at 500-700degF
Annealing is a process to soften the metal. How will that be accomplished on this casting? At the end of this annealing what about heat treat? What is the purpose of annealing anyway. I have welded probably 25 sets of evo heads, new seats, and away they went. But I know how to weld and used a soft, relatively speaking, alloy. No comebacks. Then after this annealing what about powder coating again, that will be required. After all of this processing all press fit parts will need to be replaced, new fit established.

Sure you want to go there?

Ray, going back to page 1 are these 110 heads? Was planning on using the stock 110 heads for the CVO build but thinking about using the S&S kit heads for other builds. Just wondering if there is extra beef in the S&S heads compared to the 110 heads to warrant going with S&S for the Road Glide. Thanks

these Buell heads are still running with a crack.it doesn't go deep and  it only goes 1/4 mile at a time though.

Hmmmm, dimples in the quench deck have anything to do with the crack?

Me, I would not anneal it.
Too late but I would not anneal it either for that one repair. I'd replace the head before going through all that anneal/heat treat/ powder coat crap.

As far as I know, Ray's heads are stripped of all powdercoat already.

  I know nothing about the annealing process of how it works and what if any benefits it does. I only know that Fred has used the word "annealing" to me more than a few times. I'm sure he is well aware of what it does and the effects of it. He told me he only uses one certain guy in the country that he trusts to do it...and this guy has been doing it for a many moon. 
...and yes HighLiner...I stripped the powder coating off my 110 heads. I run them in their natural silver color.

the heads on this 190hp Hemi Engineering bike were done by Fred...and the heads on it were annealed.

Nitrous oxide

I would say the dimples were from detonation and the detonation was from the nitrous.

Most quality aluminium heads, intakes, blocks and other castings under go some type of annealing and/or heat treating at the foundry. The correct process for welding and repairing them should include a repeat of the treatment. Any of the car or bike head guys I have used do this.

Some people get away without it and some just think they do. I know I have seen heads that were just welded and after time there has always been signs of metal movement.

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

I doubt a little welding will hurt them

And you have never broken a stock belt until you do and never twisted a crank until it happens. As i said many do many things, it does not mean it is right or a better way does not exist.

How many times have you seen a screwdriver used for something other than driving screws.

its easy to sit back and arm chair. I would rather just do it. instead of talk about how it will or wont work.

Do your thing Ray........ make'm believers.

  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.
