67 Camaro 4-spd, 350 with cam, headers, HEI, and double hump heads. I'm putting a new carb on the car, and in so doing changing plugs, fuel lines, filter, etc. I see the plugs are Autolite 26s and the newer, smaller 5/8 size. I think the block is early to mid 70s, but weren't all double hump heads produced mid to late 60s and use the larger 13/ hhott71. 1376 posts · Joined 2006. #18 · Jun 30, 2010. There is no discernible difference between a 291 and a 462 head. The 461 head had no chamber below the spark plug, it was machined flat when the head was made. The 461x heads though desirable for their bigger ports are basically all gone, used up and expensive.
