ok im doing a project on my 98 ls1 saturday and i have stock ls1 heads milled .025 and a comp 224/230 on 591 lift and im using gm headgaskets to you think my PVC will be ok thanks.

 

You mean PTV clearance.
No one should answer this and no one should even be asking.
This is not something you guess at, you HAVE TO CHECK IT!

I had an engine wasted because of a broken intake valve head.
Trust me, it's not worth guessing at it.

 

AAAMMMEEENNN!!! lol

he's right!

 

+1 for the answer you didnt wanna hear,,,but its true.

 

well im gonna check its not like im just gonna start the thing up and cross my fingers but i would like to know if anyone has a similar setup like mine or has any ideas incase i need to get some cutting tool to do this project in case they hit

 

If they hit or you don't have the clearance get the tools. If it all looks good don't get the tools.

 

What LSA is the cam on?
If 112/113 or 114 it will clear as long as you have stock valves.

But the guys are right, you SHOULD measure.

 

its on a 114 i bought the flycutting kit for safety measures anyways and yeah im gonna check it anyways also the valves are 1.57 and 2.02
