Stell,

Since the heads will be off and probably really close to a mill in the near future, aren't you tempted to install larger valves, or at least do some deep bowl porting in the valve areas? I would also advise trimming around the valve stem bosses and reducing the short radius sides of the intake and exhaust ports. You might also want to take a sphere or end mill into the manifold side of the ports and at least match the gasket openings and blend the ports back into the "new" valve areas.

The 305 has always suffered from poor head flow, so here's your chance.

While they're off, you might as well pull the rocker studs and tap the holes for screw-ins.
