C2 Heads - pn question

[Alan Drake]

Have what I think is a set of heads taken off a 63 motor in the 70's. Since its been a few years not sure and number not listed in my parts book,

Number on both heads 3795896 one with date code G203 other G223. There are some other markings if anyone needs them. The outside end has a single pyramid marking
Thanks

GM CASTING #3795896 heads were used on 1963 Corvettes with 250 horsepower engine. They were laso used on many 1962-65 Chevrolets with 195 and 220 hp 283's and 250 hp 327's. They did have the casting symbol that you described which denotes so-called "Power-Pack" heads. Other casting number versions of this head were used prior to 1962.
