317's + ms4 = I dont know! I pick up a set of low mi 317 6.0 truck heads cheap. I was told I could mill these heads .030" and still run the ms4 cam w/o clearance issues. Is this true? If so what head gaskets should i use? I know I could fly cut but I dont really want to if it's not a must. soooo what do ya think?
definately dont try that, it wont clear at all!

sorry... it's a 01 camaro ls1 stock internals. Can those heads be used with that cam?or is it worth it? I bought them b/c they had the same porting as the 243's but just had bigger chambers. I thought they could be milled back down and would work fine. so is this not true?

Verdad Gallardo IIRC, the MS4 on STOCK heads has .060"-.065" piston to valve clearance on the intake side. Mill them .030" and it's not going to be pretty! I'd go with a set of our stage 1 LS6 heads and have a blast with it!

Matt's just jealous because he doesn't want your car to be quicker than his. Run the heads and video tape the startup!
