Has anyone had problems with Harland Sharp RR's. I have a set of 1.7's on a FI 403 with trickflow heads had a problem with 1 of the rockers (Cyl #8) bearings came out of it. The rockers where used sent them back to have them gone over HS rebuilt the set and said as good as new. After 2700 not that hard miles engine started to tick badly. The cam is a stock ground LS7 Comp cams with Patriot springs good to .650 lift. Any info would be appreciated.

 

This is more LS7 rocker specific but may apply to other H/S rockers if they used the same bad bearings in teh aluminum rockers as they did retro-fitting the LS7 rockers.
