why wont it exceed .536? what cam are you going to run and why?

- springs and retainers are a given, you know that
- lifters, stock are fine, no reason to upgrade these unless you like listening to loud aftermarket lifters or setting money on fire
- 105# for a cam on stock heads
- stock has never broken, but youll have accelerated tensioner wear because of the springs and cam. replace it every 20-30k and itll be fine. only run a double roller if you want to set it and forget it. the only breaks are from installation errors.
