Speedmaster heads for SBM

OH! I also agree as all port is better than to large of a port. This is a seriously debatable thing. IMO, a good example of this is the TF head. A small high velocity port that delivers very outstanding numbers. How much this head feeds effectively, I don’t know. Never mind what it has done. But that’s a good starting point to try another head to see what it does against the TF.

Now, IF only, IF only I was a millionaire to just whip together what ever the net suggested to test, just for fun!
