Which material would you folks reccomend too use for valve guides?

firepower354 · 01-06-2008, 07:12 PM

Bronze for availability, lubricity and ease of machining.

LOL, I have 3 votes and only 1 person gave a reason why, nice.

Kurlon · 01-07-2008, 05:38 AM

I won't vote, but I know Kibblewhite has their own blend, AMPCO45. They list a lot of pros for it in their marketing material.

Grafixxs · 01-07-2008, 06:34 PM

Nickel Aluminum Bronze is what I was told is best...Im gonna go with that.

cyclerider57 · 01-07-2008, 06:54 PM

Ampco45 is a really high strength (mainly copper) alloy with better properties than pretty much all Nickel-Aluminum Bronze alloys. I use it for both valve guides and seats (especially for titanium valves). They have proven themselves to me through many applications. Plus, I normally run titanium valves and steel seats can have a chemical reaction at the atomic level that eventually erodes the titanium. All I run is Ampco45. In my mind, it is superior in all aspects required in the use of valve guides and seats.

I have installed hundreds of bronze guides in auto heads and these little bikes don't see many hours when compared.

Grafixxs · 01-08-2008, 03:01 PM

Ok, I did some calling around and even talked with some high end drag race guys, Cycle is right, Ampco45 is the stuff too get but it's hard too find,lol.

Kibblewhite already has 50 valve guides from std-.005" oversize. I have about 14 in a box in the garage of various sizes with about 30 seats of various sizes. If Kibblewhite doesn't have them in stock I could set you up. They are not expensive either. Chances are Kibblewhite can get them to you in a week.

They don't see the hours but auto's don't see these rpms. When it comes to guides it's always a good idea no matter what the application. Especially the exhaust. The environment valves run in with the guides is extreme: high speeds, high temps, tight tolerances, and very little lubrication.

Shoot me a price on a set pls. I want them for the new TB race head.

Do you know if you want std or oversize by a thou or so? They all require reaming to valve guide but I'm sure you knew that. I'll get with you on price.
