Does anyone have ranges for Type IV cylinder head flows with customary pocket porting and port matching? I believe is about 200-225CFM at each port. Also, any data on the effect of large valves on the flow rates? Any data on port velocities?
Yes, I know that miminal changes can produce significant changes in flow. However, in reality, there is not a lot of variations in the P/P of these heads.

Thanks,
L. McChesney

I know lots of people have tried to do this in the past using 103mm pistons and failed.

They didn't use Nickies!
