Maynard, Maynard, Maynard............
So much good advice from your keyboard this year, and then you wait till the
very end to post this! Empirical tests have proven that hard seats prevent
valve seat recession. Just about every qualified mechanic who has worked on
cars that were not originally fitted with hard seats knows that they are
necessary to prevent valve seat recession. The additional cost during a
valve job is so small that, unless the finished rebuild is going to sit in a
trailer queen that never gets used, it's truly false economy not to have it
done.
I hate to close the year on a critical note, but hardened exhaust valve
seats are a must when doing a valve job - if they have not already been
fitted during prior work on the engine. You may choose, of course, for
whatever reason, to find them unnecessary, but please don't try and convince
other neophytes to the world of engine rebuilds that your choice is the most
sensible!
Happy New Year!
(And take a spare cylinder head along if you make any long distance road
trips...........)
