AMC 2.02 valve heads:

Intake:

291 090 502
.100 71 74 70
.200 127 156 143
.300 179 201 192
.400 209 219 213
.500 217 226 220
.600 222 232 228
.700 228 238 236

Exhaust:

.100 55 56 59
.200 107 112 113
.300 135 141 146
.400 142 145 150
.500 145 149 152
.600 145 150 153
.700 145 151 153

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
