Yes 20 pounds torque on the ball retaining nut, no other adjustments. Make sure you use assembly lube on the cam and lifters. The rods and rockers should go back in their original positions with the top of the rod mating to the same rocker it was mated to before you disassembled. Use a good quality break-in oil and follow proper break in procedure. Flat tappet camshafts need proper oil and break in. Many new cam failures have been attributed to oil and break in. I'm not entirely convinced there wasn't a bad batch of cams produced as well but nevertheless you need a good oil for break-in. Most important, keep everything clean. Just my opinion I'm not an expert.
Oh yeah, a tip on keeping your rocker covers from leaking and still be able to remove when needed. I glued the gasket to the cover, gasket cement or rtv silicon, then with the head side of the gasket clean installed on clean heads and lightly tightened the rocker cover bolts. After the glue dried, about 24 hours, I removed the covers and spread a light, thin layer of silicon onto the bottom of the gasket and let it air dry for another day. Now one can install the cover and the sealant does not stick to the head upon removal. I had to remove my covers five times trying to adjust the the rockers on a full roller valve train. Finally I sent the lifters back and got a new set, adjusted them once. Still no leaks from the covers.
