Pulling the trigger on heads, questions inside.

Pulling the trigger on heads, questions inside.
I've been looking at the PRC Stage 2.5 5.3 and the PRC Stage 2.5 LS6 heads. Is there much of a difference between the two?
Also, i'm wanting a 64cc or 62cc chamber (maybe smaller if i can get away with it) to bump the compression. Doing so will mean i'll need to change my pushrod length and possibly check PTV?

Depends a lot on the camshaft your running. Dont worry though, give us a call with what your specs are & we will mill & setup the heads to your specs!

If I had to GUESS, 7.400", but until you use the tool and measure it is just a guess.
