I stopped by the local performance engine machine shop to discuss and get an idea of what the cost would be for all the machining for my 1968 J-Code 302 4V engine. We talked about what is involved and cost to rework the stock heads and then I noticed they had quite the collection of heads on the shelves. I asked if they had any early 351 heads that may make more sense to recondition than my stock 1968 302 heads. He said no but he had a pair of reconditioned GT40 heads that a customer had them rebuild and then changed their mind and went with a set of AFR aluminum. He said they were the best of the old iron heads. I asked what he wanted for them and he said $575, He also said he'd throw in the new rockers the customer donated also. Does that sound like a good deal? They are freshly rebuilt (zero miles on them) ready to go in excellent condition all done by a professional shop. I asked him what it would cost to rebuild my 302 heads and would they be as good performance wise. He said I'd spend more than that on my 302 heads and they would not be as good performance wise as the GT40 heads. This sounds like the way to go to me and then shelve my stock heads for the next owner. What do you think?
