[QUOTE=Dan Fahey;412873]What does OEM duration and overlap optional mean?

OK.. emailed Mike Baker ..and it is true.
Can use any OEM Spring.

This is Mike's response to my email..
"If it is oem design and size it is ok" QUOTE

Better get that in writing or amend it in the rule book cause look at page 49 2014 rule book,

VALVE SPRINGS:
Stock replacement per OEM spec. and must check on factory spec.
open and closed pressure

Pandora's Box
