I'm doing a 95 build on on my 06 Deuce it stock with SE 204 cams dyno at 97 tq and 88 hp

SE MRC heads  R&R porting
Woods Tw-8
CP Pistons
SE Roller Rocker
SE Heavy Breather
SE Adjustable Push Rods
SE Clutch Spring
02 Flywheel Balanced,Trued, Pined, Welded with Timken Bearings

Do you already have the SE MCR heads??  If not just have your stockers ported.

If you want R&R to port your heads then go with their matched cam R&R615.

If you want to run the Woods TW8 (love that cam) then think about Baisely or Hillside to do your porting.

Can you explain what these two would do diffrent than R&R with the heads.

What are the R&R cam spec. for 615  heads are at R&R being ported, should be finished today

<<Can you explain what these two would do diffrent than R&R with the heads. >>

R&R has done hundreds and hundreds of hours of dyno and flow testing on their products and has developed the R&R 615 cam as the ideal match to their heads.  The timing and lift of the 615 cam is much different than the tw-8.  If I am going to have R&R port my heads then I would want to use their cam and take advantage of all that institutional knowledge.

The intake and exhaust flow % would be different for sure with heads ported to max performance for either cam.  Nice thing about single pattern Woods cams is they still work well in most applications.

I know someone who used R&R cast heads with tw-8 and it was real strong.  But he switched to 615 just to try it...and it was even stronger.

The 615 is a mid range cam for a 95" in the same family as the tw-8.  It was developed off of the s&s585 but has more intake lift (.615).  Quite a bit more exhaust duration than the tw8.

Thanks for the good info. I'll have to call Art and discuss this with him, but I hope it will perform well

Duration is 247 intake, 260 exhaust.  That is the big difference vs the tw8.  Intake events are almost identical but exhaust is significantly different.

Don't worry.  The single pattern specs of the Woods cams make them very versatile.  If you already have them they will be fine.  Also R&R is probably capable of modifying their porting to better suit the tw8 if they knew you were going to use it....whether they actually do that is the question.

Talk to Art at R&R Cycles and I will be going to the R&R 615 instead of the TW8, Has anyone else run 615 on a 95 and what were the results.  Thanks

Have seen others use this set-up, and seem to be pleased.
