yes install the heads 1st then use the ps chkr.. its kinda difficult at 1st but you can do it, proper valvetrain geometry does make a difference.
I am going to mill to 59cc and run a thinner gasket to get quench where I want it, ill go with the .040 Cometics..
As far as fly cutting is concerned, I heard .080" is pretty standard....I am not quite sure though, not even sure how to measure that before hand, that is why I am asking now, so I dont screw something up big time..
any help would be ideal at this point..

i was ignorant and got a set of the 7.350 p-rods with a cam with xer lobes with a set of heads milled .030 and i had major valvetrain noise and predator steered me in the right direction.i think you will need the 7.4s also.

Verdad Gallardo stock gasket but i think it is around .053 or .054 thou thick so that is only another .013-.014 thou if you mill .030 off your heads.alot of people use 7.425 -7.450 with stock gaskets and unmilled heads so 7.375-7.4 will be very close.
IS there a write up on how to properly check PR length...i am going to purchase some 7.350 and Ialready have the 7.400 rods, so I will measure with the tool and will go by what the tool tells me...
ANy write ups?

I think I will go with the 7.350 first, we will see what happens...if it noisy or w/e I will swap with the 7.400 rods

I am where you are at right now. I have stock heads milled .025 and a .042 gasket. I came out with 7.26 0 valve lash so a 7.35 puts me right where i want for preload.
Lifters have a play on pushrod length, depending on what preload you are trying to attain. For instance Morel lifters like .025 to .045 preload, while stock are .080 - .095.

With my setup, I ended up with 7.300. Get the pr checker from summit for $20.00
" I would like to find a write up also for using the PR Checker I am ordering."
Do a search on this website, look for my name. I've written about it numerous times in late 2005 and early 2006 as have many others. Sorry, don't have it here at home or I would post it.
