The M&A that I bought used had Scorpion (sp) 1.5 ratio on them.
These are stud type rockers.
What or how much advantage is the 1.65 over the 1.5 ratio?
Got early version of M and A heads from Kenny D in around '93. Heads had stud mounted Crane 1.5:1 rollers. No rocker problems to date (2.5 season of 1/4 mile attacks).
