what i mean by that is get all new valvetrain components,
get valves, rocker arms, pushrods, lifters, springs, retainers, and cams.
....and get a built head..then you'll have a head that can withstand high hp and high rpm's

Upgrade the pushrods first...
No but really, a lot of people use the supertech dual springs with retainers, you should replace valve guides/seals/possibly valves while you're in there. Port the head too.
