Has anyone ever used Murphy's 2.0 ratio rockers with a reground cam?

(quoted from post at 00:13:40 08/27/16) Has anyone ever used Murphy's 2.0 ratio rockers with a reground cam?

I used them on my 51 A, while at the same time having the head decked, new aluminum Pistons, and a cam from Josh Blackburn. Took the A from 33 HP at 540 to 48 HP. Not sure how much was due to the rockers, but josh suggested them, so I bought them.

I have a set on my 60 with an upgraded cam. Worth about an extra 4 hp
