Alright guys, I want to check the valves on my predator. It was professionally built before last season. It has 13 race nights on it, roughly 250 laps. It has10.8 springs, and we run with a big pipe and K&N filter. What should set the valves at for max performance?
Set them , so you can just spin them with your fingers .
Some like too preload them with a dial indicator .
If you must use a feeler gauge go for .0015 .
