Closeup Wastegate before porting. It's been painted white to show outline of the flapper (which was ported so it would open fully)
Closeup Head before porting. Notice the carbon marks left by the metal gasket.
Closeup Head with metal gasket on (this gasket replaced by new factory metal gasket).
Closeup Head with fiber material gasket. Notice how much smaller the openings are. I used this gasket as a guide for porting.
I sprayed white spray paint to leave a guide against the black of the carbon.
Closeup Here's the head with the white paint on it. You can see that not much will be ported from the head port diameter, but
much was removed in smoothing and deepening the ports back toward the valves.
