I'm building a 350 for a 1973 chevy nova, and I know a guy that has some older style vortec heads. They are #14102193. My question is what are the specs on these heads, and what parts are suggested? They are bare castings and have never been used before. He bought them straight from GM. He said I can have them cause he has other projects (a disassembled 1973 porsche 911 in his attic) I plan on having mild buildup. Nothing extreme. I'd like to make these heads work for my application. Not to mention I'm on a budget (17 years old).

I would appreciate any feedback from you guys. You all seem to know alot and I think I could learn from all of you. There are some younguns still keeping hot rodding alive.
