• List of approved heads weight break for true inline valves
• Make common intake/exhaust valve rule
• BB .600-inch lift, SB .500-inch lift, solid roller for both
• flat-top pistons
• Big-Block: limit induction to 750 cfm carb or similar size throttle body BB, Small-Block: 650 cfm or similar TBD Throttle body
Keep the induction small since that is what limits hp
Pro-tree Heads up only, runaway combos get a weight penalty.
