I have a question about breaking in my comp xe268h cam in my 440. I purchased the recommended comp 911-16 springs but the open pressure of 309lbs worries me during the break in period. The manual that came with the cam said that there should be no more than 260-270 lbs open pressure during break in. Where can i buy short ratio rocker arms or light weight springs? My springs are single with a damper so i have no inner springs to remove. Any advice would be appreciated.
