intakes are cathedral, exhaust are shaped like a circle with the top and bottom cut off, so rectangular with rounded ends...
I know its a bad idea to practice on these but I have quite a bit of experience with a die grinder in removing, shaping, and polishing metal, so I'm confident there. I've done extensive research on head work and I also got a chance to talk to the guys at West Coast Heads yesterday, they were surprisingly extremely helpful, rather than hold their info proprietary one of the guys basically told me where they remove material and where not to remove material. Thanks West Coast Heads.
The only real material I will be removing is going to be the ceiling of the exhaust ports to make them circular, the rest will be simply smoothing edges.
