Here is the gasket I am running but I will not open them to that port size. Way to big and no point with 1.78 valves. Im just looking to clean them from casting flash, match the bowls to the seats and shape the ports a little bit better. as you could see the intake ports were not even uniform shape.
Here is the gasket I run, obviously 360 port size, but it matches up to the air gap intake and is a better quality gasket then the cheap metal ones.
