Anyways I got my heads in today for my lq4...
L92s that are being smoothed in the runners but how much should I have them milled for a 10.5:1 compression using stock lq4 pistons and stock head gaskets? Also am I going to have ptv issues with my 229/236 .623 .617 112 lsa cam?

You sure might, how much are you milling? We have the prc port and valve jobs setup to help p/v over a stock head allowing us to mill a little but with cams similar to that one.

Hey bud, your the one I talked to on the phone when I ordered the cam... I'm not sure how much to take off to get my c.r. some say .030 for a 10.8:1 which is fine for me. I've got an extra head to use for flycutting...

With stock dish pistons your going to be hard pressed to get it That high and not run into the huge intake valve. For this reason alone I went with a flat top with reliefs.

Those will come the next go around, right now I'm trying to get this thing going good and strong then go big cubes in a couple years when I can afford the built bottom end.
