I have those heads on my 350. From what I hear, they are a pretty light weight casting, Pretty unnefficient because of the smog shaped chambers, usually pretty low compression because they are 76 CC. They are an allright head for a stock or slightly modified engine, but for anything else, I would go for a set of vortecs or camel humps before putting any money into them. Hope this helps! and sorry if this isn't want you wanted to hear.
Anyone else know different about these heads? 71

That's the size of your combustion chambers. They are for use with cheap gas. Sounds like you have a pair of targetmasters.

I've got the same heads (goodwrench). I have an edelbrock rpm air gap and it mounts fine. I would suggest getting the CORRECT felpro high performance intake manifold gasket. The regular ones don't seal very good with this setup. I would also suggest the copper sealant. It works well. I haven't had any leaks at all since the new gasket went on. Hope this helps a little.
