Where to get exhaust valve guides for GN1 heads?

I bought these heads new in the summer of 2001 from ATR.

I have done some searching and read that silicone bronze guides are recommended to replace those that came in the heads from champion.

Does anyone know who sells these guides for the GN1 heads?

Thanks, John :smile:
Id call Tom. They have changed materials on their guides and have a really good handle on what materials to use.
just got some from Champion... the GN1 heads seems to have some one off guides, the only other guide that i found that was ALMOST the same was from some Brodix BBC heads
