Yeah I am up earl but usually am with chores to do. Also am home alone. Wife went to Minneapolis to help with my daughter and husband take care of our 2 year old Grand daughter that fractured her leg. Real nasty break. But any back to subject on hand-
The HD rockers are like the OEM rockers but heavier in crosssection in the pushrod area to aleviate breakage. Some write ups say this is not true but they are working for me and for many others. I run dual springs installed at 1.80 on a .540/.557 lift cam.

Saves you purchasing push rods too. I also have a set of adjustable 273 rockers and a set of correct push rods laying here that I may some day use but they have been here for about 5 years now and still under the bed.
Hey listen I am not telling you not to buy what ever you wish to buy. If you want to buy rollers and are more comfortable with them by all means go for it. Do what ever you feel better doing.
