Question about Stainless Steel valves.

[Fran Blacker]

Was looking at a set of Hemi Stainless Steel Intake valves. A warning sticker on box said "For titanium and custom stainless steel valves require tip protection. Sounds like you need lash and proper valve locks? What are the consequences of not using lash caps, mushroomed tips? What brand of lash caps/valve locks are best?

I don't know.

Must be a Hemi thing somehow, like depending on the cam/valve springs. There's gotta be jillions of SS valves on other applications with no tip protection and plain locks/keepers right??

What are the consequences of not using...

...tip protection.

Diapers, formula, text books, a lot of clothes, food, college fund...

I know the answer.
Hemi related stuff.

Then stop being a trolling asshole or offer up the advise. If you're not willing to help, then go somewhere else !

My cam is only .535 lift at the valve and 246*@.050.

Are your valves custom?

If so, what brand?

Many custom valves do not come with hardened tips.
If the valves don’t have hardened tips, then they need lash caps.

Not custom was on ebay and saw Manley valves box had a sticker about tip protection. Really don't want run lash caps, have chromoly locks now don't want replace them. Would non-custom valve have harden tips?

DVW, Thanks got some reading to do.

got some reading to do.

It's a very deep and detailed article.

Off the shelf stainless valves have hardened tips(all I have ever seen).

However, not all off the shelf titanium valves do.

Valves without hardened tips need to use lash caps.

That answered my question. Thanks PRHeads!
Doug very informative article. The Inconel is tough stuff. Worked in a rolling mill. The Rolling mill didn't have enough power to pull it flat, center wrinkled, looked like herringbone. At the strip furnace,25 feet long for annealing 1975* we'd pull the herringbone out.
