I have a 514 with aluminum heads and Ford recommends .025 hot. The problem is to consistently get them all set at .025 which is very difficult to do as the aluminum heads cool off so fast.

I found that .018 cold ends up at .024 hot on my 514. On a solid roller if you tighten them up you really won't hurt anything as long as you do not go down close to zero. Tightening them actually moves the tork curve up to a higher rpm which is great on a big stroker motor as it has too much tork already for a 2,400 lb Cobra. At .018 cold on my 514, the lifters are not as noisy and the car really pulls! I also do each lift individually!
