Thanks for the information. I'm used to working on old iron heads and this
difficulty of removing a plug has never happened to me before. I already
put the plugs in, but I think I will purchase a thread chaser and remove the
new plugs and clean the threads and put on some anti-seize. A mechanic just
dropped by my house to leave his daughter with my daughter and son-in-law
and he said the same thing as you. I am very careful about starting any
bolts/plugs in anything as I learned the hard way many years ago that
forcing something on usually results in a problem.
Thanks to you and all for the valuable info.
