BBC head swap to 3820
I'm going from peanut port heads to a set of worked 3820 heads with 2.19 valves. Could there be interference with the oversized valves and my forged .060 over speed pro (TRW) .150 dome pistons? Cam is only .500 lift. From what I read, both heads are 113 chamber, so no comp increase.
How much HP can I expect from the head swap?
