Bob, I also have roller rockers, but a hydraulic cam, on the 5.0L. So
no need to adjust, at least so far. And I have "buzzed it to 6,500 rpm
with the stock cam peaking at 4900 rpm, and still no problem. But of
course, I don't "buzz" the engine but a couple of times.
I happen to have a 1.7:1 ratio on my roller rockers, with stock at
1.6:1. Cheap way to add lift, without the expense, and roller rocker,
are very efficient, cooler running, by may degrees, and do much of a
more aggressive cam.
Cost me $160 for Ford Brand stamped on the rockers, made by major mnf.
