Harland Sharp Rocker Failure Pulled my valve covers and got a late xmas gift. I guess 550lbs of open pressure is too much for these little guys, shaft mount time... I figured it would be good to post in internal engine tech because the HS rockers are getting popular on ls1's.

How old are they, what mileage have they done, as mine are being installed this month.

good thing is that you can send it back and get it replaced and sell the set to get some of your money back.

550lbs of open pressure.
You won't see many LS-1 guys with that kinda pressure unless they are solid roller, then shaft mounts are a must.

They are around 3 years old, about 10,000 miles on the setup, only 2,000 with the solid roller setup.
