RAS rocker arms are very, very nice. I run them on my Coronet since it is a street engine. Can't beat a steel rocker arm for the street. But RAS has been sold a few times and I have no idea how good their stuff is these days. 30 years ago they were the best of the best.
My last two dealings with the new owners and Gary when he took the company back where bad
I've never had a problem with Harland Sharp in over 40 yrs. of buying and using their products.
I do have four sets of Speed Masters I want to try but nothing installed yet.
I have also used several sets of Comp Cams Stainless steel rocker arms and they have work well so far in the last two years
They fit under stock covers also
