Bruce,
Have you tried FelPro for the gaskets? Also are you sure about the
oil pressure? Check it with another gauge to be sure.
If you call me tomorrow I can pull up the OEM specs for a cam and you can go from that point. If you do not mind adjusting the valve train every now and then stick with the solid cam. It willl rev higher.
