I am putting a trex v2 camshaft in an ls1 and wanna know if i should check my p2v.

Everything is at the machine shop...

took .005 off a stock block
going to take .003-.005 of a set of stock 799 heads
going to do a new valve job on the heads and trim the valves(should give us almost all our clearance from milling back.)
Going to use GM mls head gaskets

Should i pay the extra money to them to check the p2v?

I think i will be fine as i thought i read that in stock form there would be .070 clearance on the intake and .090 clearance on the exhaust with a trex v2 cam.

 

pay now or pay later lol ur not suppose to mill heads at all with trex

 

Block and heads are shaved so YES check clearances carefully. My guess is you need to flycut.
