SS Valves

What is the advantage of using stainless steel valves?

stainless is stronger. Therefore, you can get the job done with a lighter weight valve, improving high end performance.

Stainless is also very hard, and will give good wear service with compatible materials such as bronze valve guides.

There are a lot of different stainlesses out there, and most of them aren't that strong.

So, stronger than what?

Most also aren't very hard compared to a lot of things.

Titanium is the only way to fly.

The only advantage with stainless is the corrosion resistance and wear properties. Actually, stainless is quite soft, longitudinaly weak and heavy. Like the man said, Titanium rules!

well, ok, if you guys want a comparision, then stainless is stronger, lighter, and harder than OEM valves. Does that help?

Could I ask where you got your information? Not trying to bust your balls here, I have never compared the two materials. What series of stainless steel are you referring to?

these are the ones I'm using in my 240 head. 1.94 intakes, 1.60 exhausts. Same length as standard. The head is thinner, the overall valve is lighter, yet it is bigger than the stocks. They are made out of what they call EV8 Stainless. Don't ask me what the minutia details are between that and the other metals. These ones run about $10 a pop. For the sixes, they do not sell enough to list them on the web page. These are the same valves used in the Clifford blueprint heads. They are lighter than stock, have a thinner head (must be stronger to cover more area with less material) and are chrome stemmed. Stellite tips.

Not going to argue, but I am convinced that it's generally true that stainless valves are lighter, stronger, and more durable than their OEM counterparts. There are no doubt exceptions on the stainless side, as well as the OEM side. The question was general, regarding why stainless? That's my story and I am generally sticking to it

Works for me!
