I have a basically stock recently rebuilt 454 with the crappy 236 peanut port heads I was looking at the Edelbrock 60499 heads which should bring the compression up to 9.2 according to them. Then a Edelbrock rpm cam or similar and a single plane o port intake.

Cam specs are 560 intake, 573 exhaust, 112 lsa.

Do you think this is worth doing till I can afford to do the bottom end up with a forged rotating assembly?

Desktop Dyno is giving me 501hp and 479tq at 5500rpm. Would the stock bottom end be able to take this?
