They're an older head, but they still run pretty good. If they are the early camel backs then they won't have the end holes for the accessory attachment. If they are the LT-1/Z28 heads they will. The early heads had 1.94 or 2.02 intake valves. The later heads only had 2.02 I believe. Both should have a nominal combustion chamber of 64cc. I personally prefer the 64cc head to the later 76cc smog heads. If they're in good shape and reasonably priced go for them. Otherwise there may be more economical choices out there once you add in the price of a complete rebuild.

 

How much do they want for the humps? Cause unless they are almost free, you could find better heads for less than it will cost you to have new valve guides and hardened seats installed. Think about some bone yard vortec heads.

 

Heads are on ebay for 75.00. Would I need to buy a intake manifold with it? I like the cross flow intake
