Valve Guides
What type of valve guides should I have installed in my 1977 930 head. I'am having the heads reconditioned, and I've seen guides that are Manganese Bronze, Phosphorous Bronze, Silica Bronze?Are they all the same?

The pro (25 years experience) who did my 3.0 heads, used Manganese Bronze guides. He recommended them highly, as being very resistant to wear, especially in air-cooled engines.

Colsibro.
A proprietary copper-silicon-plus bronze.
Is the material highly favoured by race engine makers here in UK. I have no personal experience of this very expensive F1 material... Kind regards David |

From what I have read lately...the copper in the mix is good for transferring heat away from the stem.
I wonder if some other exotic material might be better. But then the cost factor rears it's ugly head! Bob
