OK, I have a 84 250 with the integrated head. The motor is pulled And I want to rebuild with a regular head. I need to know what year heads will match. Also most of the rebuild kits I see have yearly time frames example-67-79. So if I end up with a older head will I have to order a custom kit? I would appreciate any advise as I am new to this and most of the advise I get from all of my shadetree friends and relatives is very conflictive.Thanks.
