from the proverbially other forum Wrote:It's as gasket matched as i'd feel comfortable doing.

fair enough... there can be flaws in the gasket, anything in the airstream will reduce power SUBSTANTIALLY, infact it would be far better for performance to leave the port untouched, then have a gasket interfere in the flow.

A point to all to remember, when this head, or any other porting job is mounted, the exhaust gasket is most often installed with the engine in the car. This means unless you have a small amount of foil acting as a dowel pin (to center the gasket on the studs/bolt holes) the gasket will hang a bit. A gasket match to the edge on the port will assuredly hang and intrude on the airflow. And of course.... the gasket will then interfere @ the port roof, where the highest flow occurs

Btw... the header flange in the airstream is just as bad... and it should be checked and ported if need be to make sure the flow is smooth
