59 heads were made for 239 cu in ,the A (81A)type heads were on 221 cu in engine,Like Ron said may even be higher compression than 59 type on that engine.Check clearance on piston top &cut heads so final with compressed gasket is near .050 clearance... Check CC volume of each head and let us know which has the most volume ..
