Any views on how to adjust the rockers? Googling some say 1/4 turn, some 1/2, some 1/2 to 5/8.

Some even recommend one full turn. I always use 1/2 turn.

Regarding your rough idle could it be carb related? I know you are the auther of Tuning made Easy :-), but it sounds a Little like that.

I know this may be basics, but I've had a similar condition with my "rough cam motor" for two seasons. Switched to a single plane and a Holly ultra mech secondary this season, and had rough 1000-1100 idle as I've always had. Realized that by opening the secondary throttleblades a Little using the underside idle screw , I could close the primary throttle blades a similar amount exposing less of the transfer slots in the primary bores. Boy, what a transformation - engine carmed Down a lot and now idles happily and smoothly at 800 rpm.

Just saying
