ok ive got a 1984 Chevy c10 that had a 305ci in it and it blew up and we put a 350 in it well i know that 305 heads are smaller cambers and all that stuff but i found out that i have 2 different casting number heads..the 305 was rebuilt before i got it and it had .030 305 pistons in it and im assuming what ever happened to the the motor messed up one of the heads but one casting number is 14014416 and the other is 14022801 you list both. but other sites are showing those to be 2 different size cambers..one site even showed that the 416 to be 58cc and the 801 to be 76cc and i know that cant be right because you would be able to visually see the size difference, but another site showed 58cc and 53cc and that would be hard to visually see and just 5cc would make a big compression difference...but your listing didn't list the camber size on the 14022801 number is it in fact a 58cc or 53cc because i know it isn't 76cc lol

I found this site while trying to id some heads that came on a motor/transmission combo I purchased.Excellent info! My question is how would these heads work on a 350 with good intake and headers? Any ideas along these lines,going in a 85 pick-up with turbo 350 and 411 gears.forgot to say heads are 14014416
