John,

I removed the rocker arms and torqued the 4 bottom bolts on each head from
25 ft-lbs to 40 ft-lbs (they were a little loose) and then reinstalled the
rocker arms in the exact place where they were removed from.  I think what
happend was the head gasket was compressed enough so that the valves wont
seat and create enough compression.  What do you think?

If this is the case I assume that I need to re-adjust all of the valves.
If so How do I find Top-Dead-Center.  I have the Bentley manual so I'll
follow that for adjusting.

If you can please call me. Anyone !  Cell Phone (916) 541-3045

Thanks,
