I'm specifically talking about the vette heads. I realize these aren't the best flowing head, so I realize at some pt, the cost effectiveness of it will dwindle.

So, how much would you pay for a set of these, considering there are no problems with them?

 

I got my set used for $400 complete with rocker arms. The set you posted earlier look pretty good, just need a clean up. I don't think I'd pay any more than what I payed.

 

Thanks for the info.

 

I've found around here that they're worth a million dollars because they came from a Vette.

 

I bought a set off a zz3 for $500 and they only had 3000 miles on them.

 

Yeah, no more than 450-500. They are decent heads with some porting.

Before this guy opted for true duals (non street legal) he was running 12.1 wo the juice.
That is something to go off of for a guy who can drive his car to the track easily. OH...MANUAL STEERING
