Thanks all! The unmodified tri-y will not work on 351W based on what I've read; good for 289 and 302 I understand. I have been running Hedman 88650 on my 351W and they will work with some modifications. The 88650 have oval ports but the 351W heads I have have rectangular ports so it is a bit of a challenge to modify the ports. Not sure when 351W sbf's came with oval port heads?
