SB roller rockers

heres where I am at. 6 months ago I started collecting parts for a minor engine build to drop into a 66 Dart I had just bought and just wanted to make it a nice car. Well as we all have done I kept adding things and the next thing I know I was into more then I had planned on. Anyway just before Christmas I bought a cheap set of roller rockers (PRW) from someone here on FABO. Of course they werent as advertised so I dont want to risk using them. I wouldnt mind finding a nice set of used ones but Im finding that to be difficult. I need to use 1.5 and most seem to be the 1.6.
Anyway I have decided to get a new set but was just wondering about the Mancini rockers. They are about $200 less then Cranes or Harlands. Still would like to hear from someone that is using them or someone who can confirm they are made by Harland Sharp. If so I will buy a set and if not I guess Im still looking! Thanks so far for everyones input.
