No problem Richard, I blew my number six piston due to detonation,
wouldn't want to see it happen to anyone else if possible!

4BTDC is too retarded though.  I wish I had a manual in front of me,
but I believe stock static timing setting is supposed to be about 14 or
more BTDC.  Perhaps you are looking at the spec for dynamice timing? 
But even this at idle would probably be 12-14 BTDC, unless vacuum
retard was hooked up, in which case it would be 4ATDC (yes, After,not
Before).

Regardless - for a warmed up engine of your specs, I would recommend
10BTDC static.  Remove and plug the vacuum retard.
