Jerry,

The 69 came with a flat tappet cam shaft. Ford did not use the rollers till much later. Late 80's if I remember and in the 302 to start.
You can install a roller cam in the 351w but you will have to modify the lifter valley to use the Ford tie bar retainers for the roller lifters and a few other items will have to be changed.
Stick with the stock style cam unless you are racing. It will cost less.
