WHAT EVER heads you use, Ebrock or OEM the valve springs should match the cam profile. I like buying a 'Cam Kit' which should include the matching springs. If you buy stock Ebrock heads, how will you know if the springs are compatible with the selected cam profile?

As mentioned above, the cam profile itself should work well within the expected 'cruise rpm' range and THAT will be based on the rear end gear ratio and the final trans drive gear ratio.

Nothing worse than getting a cam that works well in the 2800 rpm range and then shifting into over drive and the rpm drops to 2300. Then the engine is laboring, or you find yourself speeding up to keep it happy or dropping a gear to bring the rpm up. It can be a real hassle. MATCH that cam to your final drive ratio, this is especially important for a 'street cruiser' application!! And don't forget the valve spring rate while your at it.
