Double Hump Heads
What’s the difference between the 291, 461 & 462 heads? All 3 appear to be made with the 2.02 exhaust valve which is what I’m interested in.

Most of them will have 1.94's the 2.02s are a little harder to come by.
Not hard to have them machined and 2.02's installed but of course more money.

Good info Y2Keglide. Another good iron SBC head with small chambers is # 3987376. This is the 70 Z/28 head which has 202/160 valves AND screw in rocker studs with pushrod guide plates. Not easy to find but they're out there. 3958603 head was used on the 327 fuelies and 365 horse engines (202/160) so look for those too.
