Titanium valve check...

I run Ti valves is a Modifed motor and I will say it was the cheapest investment I have made. Disregarding the weight issue, considering the tight valve to piston clearance when trying to maximize CR, the slightest touch and a stainless valve gets bent. I have hit pistons to the point denting them with a Ti valve and they stayed straight. They are the next best thing to rubber when it comes to accidental contacting of a piston. I have a box full of bent stainless valves, no bent Ti valves.

316 series stainless is non-magnetic, and 400 series is slightly magnetic. The only time you may have a magnet adhere to a Stainless or Titanium valve is when they have hardened tips installed and it will be the only area of the valve the magnet will adhere to.

Only a handful of OEM and paper engines have Titanium valves. In Super Stock class, if the OEM valves were Sodium filled, they may be replaced with Titanium if the weight is equal to or greater than the original.

You can still pick up power by running hollow stem Stainless valves.
