feeler thread for 340 engine

I have a 72 340 engine with crank, rods and heads. The heads are not x heads but have the big valves. What would be a fair asking price . I'm thinking 750
So are they "J" heads? Is it literally just the block, crank, rods, and heads? Or do you also have some of the minor parts for it too - timing chain cover, crank dampner, etc., etc.? Is it still greasy from just being pulled apart? Or is it rusty from sitting for decades in a garage? Or, better yet, has it been tanked and prep'd for reassembly? A lot of variables here??
