There are better heads you can buy new for not much more than the price of getting yours re-built. Better flow and more efficient combustion chambers and already have hardened exhaust seats.

These can be ported and built to support 500HP. That said it won't be cheap unless you have the equipment to do it yourself. They have decent value to the restorers. You could e-bay them and buy a modern set with the $ you get for them and the rebuild and porting costs.
