I have a set of 1970 date casted 340 J heads for sale. These were the first set of heads I had on my 340. They are super clean, have 2.02/1.60 valves with hardened seats,the guides were knurled and the springs are the red ones which I believe are the next step up from the stock ones. I only removed them to install a set of ported heads, they are ready to go! Im asking $400 for them plus any shipping. I would be willing to meet someone within reason from 48169 in Michigan. PM me or call me at: 734-678-1162- I will get pics tommorrow and the exact casting dates. Greg
