I had to mill 0.272" off of a TR6 head that had been put on my GT6
engine by some GDPO.  Worked fine - still working fine, in fact.  That
took the GT6 motor from 6.2:1 compression to 9.5:1.  Much improved!

And I can personally attest to having taken 0.250" (yes 1/4") off of
one.

I think the next one I do will be a bit less radical. :) and yes, I'm
still
looking for a late head.
