The general rule I’ve always followed with my Scooby’s and other cars is the two mating parts, say the cylinder head and the manifold (headers) should have the same size openings. I appreciate that gauging the size of the exhaust ports of your cylinder head while the engine is in the car is difficult so in the past I’ve opened the manifold out to match the gasket I’m going to use. I’d be interested to know how other people gauge how much material to remove.
