Have factory original 454 mags 1988.
Redoing the heads and a valve job. Is there a cam that would give me a little bump in power. Nothing to extreme but it would be nice to get a little more power out of them?

89 454 Mags and I went with roller rockers, Comp Cams Extreme Marine hydraulic cam, heads refreshed, Edelbrock RPM air gap intakes and Holley 750 carbs. I was told that the Mercury 496 exhaust would support up to about 500hp and is the route I went finding new take-offs pretty cheap. That said I saw about a notable increase in top speed.

The 420 cam and roller rocker upgrade wasn't significant however was btwn 3 to 4 mph diff with same prop. Enough to make it worthy not a big gain by any means. That was with stock manifolds and risers.
