you need to do a clean up milling on the stud boss anyway otherwise the guideplate and stud dont seat properly. the bosses need to be milled .300" to accomodate the guide plate and stud nut.

when porting the heads, concentrate on opening up the ports to match the gaskets, like shaggy said you can use cheap stock gaskets, and removing and blending sharp edges. one thing, dont match the manifold port to the gasket as you want a small reversion dam on the intake side, and on the exhaust side you want to make the head port slightly smaller as well for the same reason. when doing the bowls under the valve, concentrat on blending the sharp edges, and narrowing and shapiing the valve guides, but DO NOT remove them as you will destabilize the valve. also dont polish the ports. leave them a bit rough as it adds power over a polished port.
