High CFM heads - What would you chose?

I agree that Rod should have not let one builder slow him down. I still think there was other factors in why the power was off on that deal.

Refresh my memory...didn’t the heads that he used for the near 800 HP deal have offset rockers? And didn’t have Bloomer heads use a straight rocker?

Some of this stuff runs together and I get them mixed up.

Rod had both a standard and offset rocker head
