stroked small blocks in the race cars?

Jim on your last engine did the piston have a dome? Must have with using 58cc chambers. Also where did your flow numbers come from? Looks like if they were the 180 Darts they have a choice of 1.94 or 2.02 valve. It seems flow numbers depend on who flows them. Did you check out the vid link I posted earlier in this thread. They tested and dyno with the head you have. They came up with different numbers than what you posted. But keep in mind I am not sure when the heads were from. they evolve over time and change. I dont know If Carlquist racing has a cnc program for your heads. I know he has a program for the 65 289 heads. No idea of the cost. I asked about the cnc program he has for my Gurney heads. Was quoted $550 to $600

I was running a dome on the piston in my last set, and will be running a smaller dome in the new set. The flow numbers I was posting were from the Dart page. With some porting, should be seeing better numbers. I have some contacts and will be comparing cam profiles when I get them and rationales for those profiles as I imagine each cam builder will have different profiles and rationales. If any of the cam profiles are considered proprietary, I will not post them on the web.

Trying to do a good job of comparing parts and putting together a cohesive build that makes sense to me and my engine builder.
