My brother recently bought a Camaro -67. The cylinder heads is claimed to be something called "mickey mouse" heads. (directly traslated)
What does this mean?

Swedish variant of "double hump" or "camel hump" high perf heads, maybe. That's one I've never heard, though.

thats what i figured, i didnt notice he was sweden till now though. Probably dumble hump heads. If they have 2 humps on the front of the cylinder heads on the radiator side they are double humps. I cant find the page now but there is a site that describes them all..

Name on heads where the intake- and exhaust valves are same size.

They are simply the SBC double-hump or camel-hump heads as stated above, and the valves are not the same size. Never saw an SBC head with equal size intake and exhaust valves. Initially, the camel-hump valves were 1.94 I / 1.50 E. Later they were 2.02 I / 1.60 E. Read this thread:

Mickey Mouse heads...Awesome.

I do a lot of engines with those heads, never heard them called that before.

In the early days the 265, 283 and 327 engines were referred to as Mickey Mouse engines- as opposed to the 348 and 409 which were called "rat" motors. Therefore, I would say the heads would be of the same design as these early engines. (Also, I think on the first 350 engines)
