Found the problem !!!! Found it in a Service Advisory update 1989!
Engine is a 2.8L, that Ive rebuilt and cammed, etc. etc. etc.
Everything is flat, etc. etc.etc.
There in the small print of the service advisory in a borrowed shop
manual: ...... head bolt threads shall be coated with RTV !!!!!!!!!!!!
Yeah OK, the outboard bolts do actually penetrate the water jacket and
the head bolt threads DO need to be sealed .... just like an old
fashioned studded engine. Last two times of extensive engine work with
(head gasket replacement) I just guess I was 'lucky'. I made up a
'jig' and pressurized the outboard bores .... yup, they are directely
connected through to the cooling loop. After several other previous
gasket replacements (dry) .... I found the friggin problem .... thanks
for all your kind advice - It at least got me looking in the right
direction.

thanks
