[AJD] GP valve guide problems

[John Boehm]

After a private email to Greg, I found out that he
indeed has the new valve guides, so I put in an order
for 4 of them. My son pressed out the old guides from
the block this afternoon. Hopefully, Greg is right on
the guides being worn rather than the valves. Can't
wait to find out! Thanks for the help,
