I read in circle track awhile back that it helps to ground the cylinder heads to the block or battery with a good ground strap. The head bolts going into the block having thread sealant on them don't give a good ground for the plugs.

How many miles on the car? Could be worn bearings or
bushings in the distributor or a worn shaft or
possibly even the drive gear.

With the cap and rotor off, you shouldn't be able to
move the shaft up and down or rotate it more than a
tiny amount. Try wobbling it sideways too.
