I'm new to this small block stuff do they all have heat risers on them?Will theyfit a A-body?Can you give me a ballpark figure?

this one has the heat riser, but you can remove it if you like. they will fit no problem. they came off a 70 duster. ( they are the wrong ones for that year) they will fit all a bodies. i was thinking like 80.00 plus shipping. where you at?
