I had the rocker covers off yesterday to check the valve lash and thought I would post an update. It's been 8 years and 35+ thousands of miles with too many over revving runs (7400rpm) and the Crower solid lifters and roller rockers are still going strong. After the pain I had with the comps, I was ready to give up. Thing are so good with the setup I only had to adjust two valves since the last time 9000 miles ago.
The old girl is still going strong, it's in better shape than I am.
