After a little research, I have come to the conclusion that NO holes need be bored in the 351W heads in order to bolt them onto the 289-302 blocks. To wit: you could still buy a 289 HiPo shortblock
The special pistons are hard, if not impossible to come by, as I don't think they are made any more. (I could be wrong though) Could be custom machined, maybe check Hemmings. Ramon, ask Dan Walters.

I've got a pair of C9OE's on the shelf myself. These are the same castings I ran for about 4 years in the early seventies, on my HIPO block. My first set was lost to over exuberance in developing hig
