Checking valve spring heights.

The +50 installed height stuff from Comp is only available in the 10* Super lock, in single groove form for a 3/8 stem. Pioneer offers 7* locks in single grove. But this is useless info. Your not going to find a 2 grove offset keeper. ^^^^ mopowers said, get new 4 grove valves and the keepers to go with The 4 grove exhaust.
