[QUOTE=Mike Keener;499897]Jim Mantle,

No they will not be tossed because this engine has been deemed legal by NHRA since it's inception in 2012 for either Stock Eliminator and or the Factory Shootout.

The reason I brought this up goes back to the rule book, I don't see any exemptions for cars originally equipped with titanium parts, valves or retainers.

"engines OEM-equipped with sodium-filled valves may use sodiumfilled replacement valves. Titanium prohibited"

"Any valve spring permitted, provided no modification to head is performed. Steel valve-spring retainers mandatory."
