The following cam fto EPS is advertized at Brian tooley.EPS CAMSHAFT - STROKER - 34456143
Specs: 244/256 .629"/.604" 114+3 This cam is intended for 400+ cubic inch LS engines that are utilizing cathedral port heads and a stock style intake manifold (i.e. LS6 Intake, FAST, MSD Atomic, etc.). This cam will provide a choppy idle, but still retain some level of streetability. This cam has made 596 RWHP when coupled with TFS 245 CNC LS cylinder heads in a 2001 Camaro with a 6-speed manual transmission.
It has 22 degrees of overlap. Mij 239/254 has 18. Could it be that the camshaft is quite ok? Because changing the camshaft and lifters and pushrods makes things a lot more expensive.. The mamo heads even need roller rockers.

That cam isn't that different from your existing camshaft. I believe this is your existing cam?

I would figure out your PTV with your existing cam, consider swapping out to a cam with less exhaust duration and a more even split, mill the existing heads/go to a thinner gasket to get the CR up more and re-evaluate before dumping a bunch of money into a new setup.
