Head Games!

So far I’m seeing 10:1 compression TRW forged pistons but am going to assume that the goal is 10:1. If so, some head milling and careful head gasket selection is in order. The goal is 12 second car with 3.91 gears and a four speed as posted in the cams away thread. I don’t recall the tire size being used, but tires and suspension is going to play a large part in a 12 second car. I’m thinking the J heads with the proper cuts in the chambers for 2.02 valves, bowl porting (I would do a good gasket match at this point to) are good for around .530 lift. So to really take advantage of the heads, adjustable rockers aren’t a bad idea. It really would help to consolidate these threads, because what you want is doable in several different ways, but it helps to get everybody on the same page.
