I have a GM Corvette parts manual covering '53 - '78.
Is there something specific you would like to know?

Re: Where can I go to look up original GM Part mumbers?? (Alwyn678)
heres some info i found...
"041" – 3947041, also 3947041X. A good performance head. They were found on 1969-1970 302 and 350 engines. They had either 1.94/1.50" or 2.02/1.60" valves, 64CC combustion chambers, DO have accessory holes, I don't have port volume data for the regular 041, the 041X intake port should be 165CC's, the 041X exhaust port should be 65CC's. These heads have a single somewhat triangular shaped casting mark (slope on the upper left).
"041" – 3947041, also 3947041X. A good performance head. They were found on 1969-1970 302 and 350 engines.
