Will 66 289 heads work on a 351W? Are their any mods needed? I had planed to use a 302 stroked to a 342 (standard bore), however the thought of more cubes and less money make me wont to lean towards the 351.
I just done a swap 289 to 351 with ported 302 heads.
all was needed to drill the holes for the bigger head-bolts and drill some steam -holes in the block.
Think you dont need to drill them in your stroked 302 , but for sure check with a head gasked and have a look to that water-passages !
longer pushrods you need on a 351 block because the bigger deck-hight to a 302 or 289!
If I am wrong please correct me .
