ID these heads?

Oh, I see they have the "360" cast in to them. Those will be the 340/360 1.88" intake valve head not the 2.02" T/A.

The T/A heads had offset pushrod holes and did not have 360 cast in. When the 360 came out for the 1971MY, Chrysler put the small valve 3418915 head on 340's and 360's.
