I also have Edelbrock's 2x4's intake manifold (54501) for the same engine. What I would like to know is that will these heads and intake manifold by chance fit on a 389 {1964 389 Block}. I noted the bolt pattern is certainly different. But when you match the cylinder head gasket to the 64' block and to the 65' cylinder head surface they do match up. Is there any other issue I may have to deal with such as water ports which when focusing on the problem seems to be the only problem. If not, then I'll go with a later block. Thanks very much if any of you Pontiac fans (or certainly others) can provide me this important background information.
Don't use original-type pistons. The valve reliefs of the 389 pistons- if they're similar to the originals and not aftermarket or the dreaded "8 relief" pistons, will not align w/the valves of the Edelbrock heads. This can be a real problem if using a high lift cam.
