Hi and thanks for the speedy response

its was just the heads and a valve job. the head gaskets were
replaced.

the engine was warm when I changed the oil filter.

the oil pressure started to drop after I put the engine under a load.
3500 RPM's and the oil pressure dropped to zero and the red warning
light on the dash board went off


Hate it when that happens. Forget everything I suggested. You have a
problem.
