If anybody needs or want DP heads ,I have got a pile of them.  No dropped valves. I would say about 95% or better are in good shape and complete with all springs/valves etc. but need at least exhaust valves to be on the safe side.  These heads were "take offs" during long block rebuilds when new heads were used. I'm tired of falling all over them. $10.00 each and you pick them out.  David- 894-3374
