360 swap to adjustable rockers

when i swaped to the adjustables i bought the proper length pushrods (i dont remember the length)but i had some troubles with them being too long and had to do some slight grinding on the bottom of the rocker so it didnt hit the cup. when i made the swap it was beacuase i was breaking alot of the stamped rockers in my circle track car.they did solve the problem.
