If you have the room for the exhaust lift, the
[email protected], 269 @ .006, .455 lift Howards cam would work really well for your combination. But I just caught were you said EDELBROCK PERFORMER RPM HEADS as part of the program. That's going to bump your compression up and give you room for a lot of lift. It's a complete game changer and will require aftermarket rockers, too. If you could swing it, a retrofit hydraulic roller would be idea.
