Hi All,
I've got a 1984 Camaro Z28 that I want to put a 350ci in.

I just purchased a semi complete engine that is in pieces.
The engine came with cylinder heads casting # is 3884520. I've searched the web and I've only been able to find limited information about these heads. They appear to be 283/327 heads with a 60cc chamber,and 172/150 valves, beyond that, there doesn't seem to be much other information floating around them.
The older gentleman that I bought the engine from claims that they are the heads that were on the engine when he had it installed in a '55 Chevy many moons ago.

I would like to make the 350 a 383 stroker and I'm in search of information about the heads to see if they are suitable for such a thing. Does anyone have any information about these heads that they would care to share? It would be much appreciated.

thanks
