Cylinder Heads

[8kgold69]

I was given a set of cylinder heads # 3932441, dated M 20 8. Anyone tell me what these original fit? Also what are the pros and cons of these heads?

3932441 should be from a 69-70, 350cid, 76cc chambers
This page has a good overview of casting numbers:

Thanks for the reply. I went to a web site that stated these heads, 3932441 were used between 67 to 72, 327 ci and 350 ci. The number does not show up in any of the NCRS books, so its not for Corvette. I thought it said Camaro, Monte Carlo, or Chevelle. Can someone tell me what model Chevrolet these heads, 3932441, diffently fit?

Thanks

They'll fit any small-block (including a 400 if you drill the steam holes), but with 1.94" valves, I wouldn't recommend them for anything but a 327/350/400. You won't have much compression with those big chambers, though.

Were these heads used on Camaros, Chevelles, truck, etc...? I know they are not Corvette heads.

They were used from '69-'74 on 350's in passenger cars, Nova, Camaro, Chevelle, and trucks.
