Edelbrock / RHS heads, or go BIG block and put it to bed!

Unless you spend money to port the Ede's, and you'll be in ~600 in porting to get them to the RHS level, buy the RHS 2.02 head Brian does at IMM. Better components, valves/springs/retainers, than the ede and MUCH better quality of work on them. He can cut them to whatever chamber size you want to get the static compression where you need it.

You really need to correct the ede machine work before running it.

I'd stick with the SB.
