Bruce,
The heads and intake are matched together and should stay that way. The only thing different from the medium riser heads is the placement of the port.
If you are running a solid lift cam in the motor now the person that set it up should have installed the correct plugs used for the solid cam in the galley.
What specs are on the cam you are running now? Give me someplace to start and I will try to help.
With your engine it should spin the tires in second gear idling off the line if it is set up correctly.
I rebuilt a H&M 427 side oilier years ago with a 2x4 with medium riser heads and a solid lift cam that would spin the tires in fourth from a dead stop. It idled well and pulled to 6,500+. It did have the NASCAR crank and rods and that did help with the high rpm's but the cam you pick is the heart of the engine.
What do you mean low oil pressure? Most FE's will idle with 15-30psi and top at over 80psi depending on how it is setup.
