Probably won't be too hard to Zero deck those suckers and run a .028 head gasket.

The lift won't be the problem, gonna need to keep the duration down though so short duration with fast lift.

One thing I like to do when running a high compression motor is to chuck the exhaust valves in a drill press and polish the heads, start off with about 600 grit sandpaper and work in steps down to 2000 for a mirror polish, this keeps them from absorbing as much heat and helps keep detonation at bay. Remember the ex valve is one the hottest place in the chamber (as long as you get rid of the pointy thing between the valves).
