HS told me that their rocker stands are 1.375" high on center, while the stock Ford stands are 1.420" high on center. If using HS stands does this difference appreciably change the valve geometry? Anyone had any problems using the HS stands? They don't have the horizontal cut that allows the stand to "grip" the shaft.

.......problems. I do recommend using studs and not bolts, JMO, Rod.
