Funny that TAPimp had a friend ask me if I would tune his car when it was ready
I guess I'll let him take it to LG. Maybe the homers can keep the tuning stuff out of the thread. I offered to bet anyone regarding the tuning so unless you're ready to lay down $$$ about the matter then please quit trashing my thread.
Back to the subject....
Regarding geometry - the pushrods are hardened 7.4" and brand new Comp "R" lifters were used with the PP head install per Lou's recommendation. The rocker arms were tightened to the correct specs and the springs were obviously setup by PP. A compression test was done ~ 1 month before the install and everything was good.
The MLS GM head gaskets were used with OE GM head bolt sets and everything was torqued and retorqued to the correct specs. There are no P to V clearance issues at this time.
If the power doesn't increase substantially at Lou's by either tuning or dyno methods used then they are probably coming off in favor of someone else's 5.3L heads to see if in fact that could be the problem. At this point I'm still not sure what to think

Chris,
The crane springs does not require the comp R lifter.They hace 120lbs on the seat and 350 open.

Since when did personality override talent?
Chris is very knowledgeable when it comes to the LT1,LT4,LS1/6.
He does this all of the time. I found him to be quite personable myself!
This guy has tuned a ton of Fbod's & C5's to include Z06's.
Again, this is "my" experience with him & rest assured when i do H/C , Tq conv, he'll be there to set it up.
Have you actually met the guy??

That's what I'm thinking. If he used stock type rockers and 7.4in pushrods, I bet his preload is too much and may be hurting him.

I know I've seen a thread that said you can run comp lifters with a non adjustable valvetrain, but my guess is that it would be hard to get the 0.0 to .010 preload that the R's like without having a adjustable one.

FWIW, your 'before' compression check doesn't mean squat right now. You need to do an AFTER check.
If your preload is incorrect (not the torque, the preload), you are hanging valves slightly open when they're supposed to be closed. Even ever so slightly open can have a huge impact on power. My opinion is still that your rocker geometry is incorrect.
I posted earlier in this thread that you should do a compression check. Has it been done yet? I think you will need to do one of 3 things - different length pushrod, shim the rockers, or go with an adjustable valvetrain.

I agree,You have to start the check process somewhere.I do not believe the heads are the problem.To many other folks have made good power with the exact same heads.
