A roller cam is not magic. The small amount of return you get under the curve is not worth the price to convert. Half a inch lift ,is a half inch of lift. The spring pressures are there. You can reduce them with multiple valves like modern 4 valve engines.

The edelbrock crate 420hp RPM or the Mopar crate 380 HP 360 both have roller cams. Both are well designed and not for heavy vehicles. Neither make a great road engine. To go bigger heades and cam only makes driveability worse.

A roller cam is not magically have 5000rpm powerband. No carbureted build is. A built hot small block usually doesnt get organized till 3-4 k rpm.

It is getting easy to spot the experienced.
