Titanium Valves Allowed in S/S? - Page 2

Keep in mind when a Ti valve breaks the carnage can be twice as bad. Maybe that's why the engine builders want it?

I am for them in both super stock and stock(Jr Super Stock), It is a choice, no one is making a person us them if they do not want to.

Already allowed in many S/S classes. SS/AS, SS/BS, SS/CS. Probably others. Dyno

Exhaust only or intake too? BTW, other OEM valves have hollow stems too. You should see the hollow intake valve heads that are lazer welded together, neat stuff.

Chris,

At the time the rule was implemented for the Ford 427, there were no other OEM applications with Sodium Filled valves.

ZERO but the NHRA wizards were not aware of this till late last year. They had no idea on what was in those engines.

Terry that is what they are in 2010. Should go a little farther with the rules. Same as S/S except for 9 " tires, stock manifolds and stock valve lift.
