Some later '71 340's came with J heads with 2.02 intake valves.Not too bad a deal. They're '72 340 heads which are exactly the same as 360 J heads, including the small intake valves. Choke and cup are gone, though, so you wouldn't want to buy this setup for a daily that's used in cold weather. Those pieces are both rare and very expensive since they're '71 only.
