Max horsepower with EQ heads?

I think you would need to solid plug the pushrod holes, offset drill the plugs, cut out the pinch entirely, cut the stud mount bosses shorter and grind out the boss material completely from the port inside. Then design a shaft rocker system mount, for offset rockers, with what you have remaining of the stud boss threads.

The problem here is the way the EQ's are cast. It is not possible to easily plug the pushrod hole as it is an irregular opening in the EQ's. I have begged Eric @ EQ to send me a pair of heads that "missed" the pushrod machining operation to no avail. I also have asked Eric to cast these in aluminum and price them below Edelbrocks and watch Edelbrock cease to sell any smallblock heads at all. Apparently an aluminum version is a real possibility.
