The problem is with the notches in the pistons. The polys are notched differently than the hemi. Since there are no 259 hemis, you will have to have the notches enlarged by a machine shop to be sure the valves will clear, or bore for 270 pistons.
Early hemi to late sb Mopar trans adapters. Precision billet parts for early hemis.
I would assume 241 Hemi head gaskets.What head gaskets to use: 241 Hemi ones or the 259 Poly ones?
But can anyone validate this information?
