Thank you! I've been working with another guy, but they are really draging their feet. So I found a california company that will possibly use the same linkbars/bodies that we use for solid rollers to make these hyd. rollers. We will try some I hope in a month or less. Same basic engine we did for CC, but hyd. roller lifters/cam, and maybe some porting on the RHS heads to see what's there. I will keep you guys posted. Brian
