I just realized you are quite a long way away from cali. Sure you could find a pair here but shipping would kill you. I suggest placing a want add here and see if a local member speaks up.
I have a couple but they are for the rounded "contoured" piston.
You need whare known as "e" type heads. They have a d shaped combustion chamber. As opposed to the round circumferance design used with a contoured piston.
