$450 is cheap. Even if you run the 3/8 valve and don’t port them, they still move a lot of air. Rockers are more expensive.

Nobody in their right mind is going to buy a 48 degree block, expensive rockers, pistons, and an intake to run a head that flows less than a ported Speedmaster head. They are pretty pathetic stock.
