If you're looking for "cheap hp" and not building the engine (i.e. pistons) then using a smaller 58cc chambered head from a 305 HO along with a steel shim headgasket will raise the compression a bit and give more HP, plus the 305 heads will flow a little better...

What casting numbers should I be looking for?
Any idea what the compression would work out to with them? I am running flat tops and I believe the motor is rated at 9:1 or 9.5:1 with these heads on it from the factory.
