    I run Lunati beehives. Never had any probs with them in 8k... (knock on wood) This is with a TR224 cam. They are good for .600 lift too, and spring pressure is perfect for lower lift cams. Remember that too much seat pressure can cause alot of problems.

    I just ordered the Lunati dual spring kit with my Comp XR275. 222 224 .566 .568 112. They should be good. What's the easiest way to make sure I get the install height right?
