Re: 327 rebuild 882 heads
I am not a cylinder head guru, but the flow numbers show that the 882's are quite comparable to the Double humps. The 882's are from the smog era, so the chamber size is large 76cc vs. 64cc's on the double humps. The advantage here is simple, compression. Do you know what pistons you have ? If you ran domed pistons etc. you could keep your compression up, where as the double humps with domes would give you more compression than you would want on the street. Many of the old double humps do not have accessory bolt holes in the ends of the heads. These are not needed on a '67 or '68. In a '69 they become an issue. Compare what your compression will be with both heads and determine what is the best for you ! Aftermarket heads are your best choice, but it will cost you.
