sliding I need valve guides!

I need a new valve guides for my #113 heads. I've searched
on e-bay and all stores (online) that I know of but I can't
find anything.

How is it possible that it's so hard to find valve guides for
L-98 engine?

I have pulled one guide and it measures
L = 2.060"
I.D. = .343" or 11/32"
O.D. = .557"

The closest that I've found are .5643" O.D: and a little bit
longer. That would be fine, but price is $8.50 each, plus $150
for shipping (they only ship with UPS).

Anybody know a source for valve guides?

I've talked to machine shop that does all my work.
Problem is that this engines are really rare over here,
and I can only get custom made guides.
That takes both time and money.

If I won't find any other solution, I'll have to do it,
but I'd rather buy them if possible.

I've seen a lot of Honda guides for $70-80 on ebay, manganese bronze,
so it's really odd to me that there are no for L-98 SBC.

These are 11/32:

Normally, machinests I deal with do not replace the guides. The ream them oversize and insert bronze liners.
Removing the cast iron guides from the aluminum heads often pulls a small amount of metal with them that will result in a poor press fit of the new ones. Liners are very inexpensive, and work very well. On future builds, they are slid out, and new ones re-installed just as easy.

I've heard that. I've also heard the guides like to fall out of the 113 heads, and the guys I've spoken when like to install new guides.

6 in one, half dozen the other I guess.

I have heard of seats falling out, but the guides are new to me. I guess we are at the mercy of the machinest's preference during refresh time.
They always get the final say I guess.

I believe that I've found guides. It's from ebay parts supplier that I allready ordered some parts before, and he's really straight up guy. He doesn't have them offered, but he was willing to ask arround. I should have them shipped to my doors for approx. $100. It's for bronze guides. Cast are cheaper.
