<VV> Valve seats

[Mark Durham]

I concur with Lon, if there is no pushed metal at the seat to head
interface in the ports or combustion chamber, REGARDLESS of history or
no history, they are OK to use as long as they have not been ground too
many times! I've done thousands of seats in automotive and aircraft,
and seats that begin to come loose at temp will move and push the
softer aluminum. if unsure, take some pics and send them. Mark Durham

No No NO!!   Do not tamper with factory installed valves seats in
ANYTHING if, after careful inspection, they appear fine.
