The 291's are 3196291, 1970 51 cc chamber heads, the 090's are 1973 58 cc heads, and the 502's are 3220502 1974 60 cc heads, I have tested an example of all 3 combustion chamber sizes. The 291 and 090 heads have a multi angle valve seat, the 502's are utterly stock. There is no porting on any of these. They were all tested as identical as I could make it - same port, valves, inlet radius plate, flow bench, day, operator, and bench temperature. The correction factor for the bench temperature is a reduction of 1.6%, I couldn't be bothered adding it in.
The shrouding on the 291 heads really hurts the flow, it really surprised me. The later 60 cc chamber heads probably flow the best, I figure a valve job would make up the little difference with the 090 heads.

they are soo close fuzz that a mild port would tip the scales, i will run 0502's and use guideplates and port them and save the supposedly good heads for the other guys
