the LT1 and LS1 heads won`t bolt on the early blocks, the water ports on the heads don`t line up with those in the block. as for the ZZ4, if it`s not reverse cooled, and I don`t think it is, the heads should work.

The ZZ4 heads are production late 80's ....early 90's Corvette aluminum heads with better valve springs. They are 58 CC and have no provisions for heat risers. They also require the 87 up center bolt valve cover.

Without knowing which pistons you have, I cannot say what the compression will be but it is a great bet it will be higher than what you have now.

A better choice is the FastBurn head. It is 62 cc and worth 30 more HP than the ZZ4 head. It has larger valves.....and is new technology. They also take BOTH styles of valve covers. The old pre 87 common kind or the newer 87 up center bolt kind.

Thanks this is a lot of help, good info. I haven't bought any pistons yet. This project is in the beginning stages. Wife bought me a 64 NOVA for fathers day and I'm just getting a start on restoration. I,m building the motor in my head first, then in the shop. So far I have a 68 large journal block and double hump heads and just purchased a 3.250" stroke forged crank the rest is open for thought.

Investigate header availability for the ZZ4 D-port heads in a 1st-gen. Nova before you get *****-deep in the project. A guy on the www.stevesnovasite.com 1st-gen board who lives near me is having a boat-load of trouble finding headers for his '66 that will fit D-port heads. Someone already told him theirs would fit, but when he bought them, he found out different. I know another guy who has had thread-stripping problems with his heads. He finally Heli-coiled every hole. His were bought used, & I guess the factory scrimped on the anti-seize compound. Other than that, he likes them a lot. There's a set on EBay now.

I put a set of aluminum heads on my 69 camaro in 94 and have never had any problems with them. I don`t remember what the CC`s was. but they are gm raised runner, D port, angle plug heads, and take the pre 87 valve covers.had to use a double intake gasket, and do some gasket matching but they work good.
had to use a 1/4 inch spacer under the header flange, and extra short plugs.

They have very large valves, and really tall intake ports, and are very closed chambered.
