I have a set on my 360-1 heads now. Superior quality and work great. I had a set of the junk crap made by Indy and broke one just driving normal around the block. I looked at all the other jobbers that sell rockers. Called Hughes and asked about them. Spoke with Dave " I believe that's his name " and he went over how they are made and told me if one breaks from any factory defect to send it back. No time line . He said
he 100% stands behind the quality of his parts. So far so good. I have a stroker engine that I spin to 6700 with a mild 6.50 lift roller cam and they stay adjusted pretty good and no problems at all. Just my 2 cents
