New 5.7 harland sharp rockers

Not sure what kind of set-up they were running, but I can tell you that I've got their Adjustable set-up on my 5.7. They bolted on with no clearance issues, and have seen 8000 rpm with a solid roller cam. They definitley put alot of effort into the design as they do with all of their stuff.
My valve springs have about 550 pounds of open pressure, and I'm getting ready to change the springs to get 850 pounds of open pressure. This will definitley put them to the test! I have run Harland Sharps on my small block for 11 years now with THOUSANDS of passes with no failures. I can assure you that these rockers are high quality.
