Randall,
Thanks for forwarding my email. Interestingly, when I showed the head to my
machinist, he said he could clean the head without destroying those tubes. I
have my fingers crossed! He is a pretty good guy and has been doing this
stuff for years and years. He had asked me if I wanted to mill the head when
I mentioned I had a set of 87mm pistons and I told him I would check with
you guys first. He had suggested taking off 0.050 which was the amount most
people had asked him to remove. I have no idea how that would effect the
valve train but maybe you or someone else had done this and could shed some
light on it.
Thanks,
Dave Connitt

I've never done it myself, Dave, but the local racers tell me they have.
Sealing the new tubes is apparently somewhat difficult, but not impossible.
ISTR mention of home-made swaging tools and penetrating Loctite.
Ken Gillanders would be a good person to ask, so would Jack Drews. I've
copied
them on this message, hopefully they'll be able to tell you more than I can.
