Trying to repair a damaged air cooled motorcycle cylinder head. With
largest oversized (O.D.) valve guides, still unable to get a tight fit.
What would be a suitable material to make a sleeve out of? I have some 6061
aluminum, but not sure it will stand up to the high temperatures, especially
since the affected valve guide is on the exhaust side. The valve guide
material is a silicon bronze and the head is aluminum.
