[TR] TR head rebuild

[wbeech]

Allen,
On my head the plug is tapped, looks like a 3/4 pipe thread but it may be
straight, I have not tried to replace it yet.  I had a bad head and decided
to try to drive it out but only succeeded in dropping it into the head.  

I should think that a machine shop could easily remove this and you could
then install a pipe plug or straight-thread plug as others have suggested.
Try McMasters-Carr for a 3/4 hex-drive plug similar to the one used for the
oil gallery on the block, I bought it from Mc-C, they called it a 3/4" dia.
set screw!

I have a pipe plug in my TR4. It was done a very long time ago, but I almost
think that it is already tapped, in spite of the fact that it looks
otherwise. Don't remember why or how I got the aluminum plug out.
