MS4 w/ 5.3 STG 2.5 Heads???
I have a set of TSP stage 2.5/5.3L heads and am now wanting to install a MS4. My short block does have forged internals with 2cc relives. Will this be a problem cause of the lift or will i have to flycut them?

Naw just cram it in there you'll be ok. I'm running Stage 2 LS6 PRCs with the chambers cut down to 59cc+.040 cometic with a MS4 and I've got diamond pistons with the -2cc reliefs. So you ought to be able to shave them, quench them and cam them to your hearts content. Have fun.
