What do I look for? I'm not even sure what the heads are that I have now. The engine should be out tomorrow so I will be able to check them out and see what they are. The engine is 70's truck engine that was purchase re-manned and put into this car in 2008. Right now it has probably less than 30k miles on it. So, it's still pretty fresh. It hasn't had a tune up since 08 and it still runs great! It has 10:1 pistons, Edelbrock 4brl intake and carb, and shorty headers. I'm not looking for anything crazy, just wouldn't mind having a bit more "juice." If there are some other bolt on mods that will do that, I'm open to it.
Anyway here's the car. Finally getting to it. LOL

Edit: I read some of the threads listed below in RE to 351w heads. Good info. But I welcome more, newer...

 

Pretty much all of the 302 performance heads fit the 351 (you may need to drill the bolt holes out slightly larger from what I remember). It really depends on what you're planning on doing but there are a lot of choices out there.

 

Thanks, man.
Where do I find the casting numbers on the current heads?

 

This might help you out a bit

Interesting read. Thanks again. But,if I'm looking at that correctly, ya gotta have the heads off to see the casting numbers???
