Tunnel Ram on a 496

[Garys1969RR]

I am planning to put a 2-4 barrel Tunnel Ram on a 496 (383 stroked to 4.25") this winter. I have a set of Stealth Heads on it now, but also have a fresh set of Stage VI Mopar aluminum heads. These have been ported to some extent. I am wondering which head would be best for this set up? Any ideas? Do the Stage VI heads flow better than the Stealths? This is a strip only car, with a roller cam. I will be checking lift and duration on it soon. Thanks.

get the head flows and cc's what pistons and how far down the hole hand calculate your compression ratio

This motor was put together with Stealth heads, M1 intake, Holley 1050 Dominator, and a roller cam when I got the car. So I plan to pull a head, check the chamber volume, see what the pistons look like, and go from there. The seller claimed 14 to 1 C Ratio, but we'll see about that. Will also check cam lift and duration@ .050", and fix an oil leak on the timing chain front cover. Then will reassemble it using the Tunnel Ram, and possibly the Stage VI heads.
