4 threaded holes in head

["Larry Daniels" <ldaniels@vbe.com>]

Regarding the threaded holes in the exhaust port, I had a little bit of
difficulty in finding the correct size socket head set screws to plug the
holes (bolts sticking out were too ugly).  I ended up having to buy them in
quantity.  I also have a hi-temp thread sealant that withstands gas and
chemicals.  If anybody else needs them, I have quite a few left. Just e-mail
me off-list.
