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.

Call TSP and ask them. Their heads, their cam, they'll know exactly what to do to maximize it.

I'm no expert with this stuff but i read yesterday that you have to fly cut using 5.3 heads and a ms4. Just my lil .02.

I wouldn't worry about it if you have a -2 reliefs. That's if the heads haven't been messed with.
