The PC of the part number gives this away as ProComp SBC heads. They should measure as 190cc intake runner and a 64cc head chamber. If these are not mounted and you want to use them on your engine you will need a pushrod that is .1 inch longer than what you have now if your current heads are stock GM.

The 190 ProComp has so-so low lift flow but very decent high lift. A little port cleaning and using back cut intakes improves the low lift flow a lot without harming the high lift flow, needless to say if taking them racing they respond to higher lift cams very nicely.
