Here they are on the bench.
These heads flowed really well from .300 to .600 where they leveled off. This is at .700 where they gained just a few cfm.
I always test heads .100 past the max lift of the cam being run.

Early Twin Cam Screaming Eagle heads with the ports they carried over from the Evo SE heads. Tested it with different manifolds. This one is a Super G with a stock port size hence the noise. It flowed the same as a port matched manifold but I didn’t record that one. 😬
