When they first came out the KRE d-port heads were reported to flow 226 at .500 lift on the exhaust right out of the box.
( High Performance Pontiac magazine / Feb 2004 )
As cast they had a 88 percent exhaust-to-intake flow ratio at .500" lift. With TA Man's intake port work and leaving the exhaust ports as is the ratio came down.
