I have a 94 camaro z28 m6 with all bolt ons and lt4 hot cam. What heads would work great with my cam over my stock alum. heads. LT4 HEADS would those give me a huge increase, any recommendations??? Also how much of a gain in horepower I'm I looking at lt4 heads over stock lt1 alum??

 

If you get the LT4 heads, you have to buy the LT4 intake too. They have raised runners and are not compatable. You would save money and have better flow #'s if you sent them to Lloyd Elliot to have them ported. I think he does them for around $5-700.

 

If you can wait, the Trick Flows are a good choice and dont need the lt4 intake (but you should get your stocker ported). It has some good components (but will lower the stock compression) and should be good for plenty of fun. Much better deal then the lt4-s hands down.
