Lifters lifters lifters............

If you get old ones it will be hit or miss wether or not they are good. New ones are only $100 from ford and you could always use them in the new engine.

Hyd. rollers are the same between the 351w and the 302.

J/Y's should be pretty cheap. Just buy more than you need, and try to find a motor with cleaner internals (this indicates the oil may have been changed more often).

When I built my 351w, I used the stock 302 rollers from my 5.0. I must have put more than 210k miles on those lifters.

If new ones are in the budget, then it is worth picking up fresh stock.
