Does it smoke out the pipe? If so, is it grey or black?
You should also check the sparkk on that plug.

I believe I am running the NGK D8EA plugs. All four are brand new. I would have to check when I get home from work to check for sure thats what they are but I am so certain thats what they are.

Not necessarily, unless you first determine what is causing the smoke. While it is possible the seals are leaking, it would be rather unusual for the problem to be a gasket. A leak-down test would help nail down the cause if it is in fact an oil leak. Without first diagnosing the cause of the problem, you're taking somewhat of a shot in the dark hoping you fix the problem by replacing parts. Ed

Can perform a poor man's leak down test by introducing compressed air into a spark plug hole and listening to where it escapes from the combustion clamber. This may be done at TDC or any other cam positions where both valves are fully closed. Top dead center (TDC) is when the piston is at its highest position. An easy way to tell TDC is by alignment of the T mark with the case mark when viewed through the timing window.
May introduce a spurt of compressed air by using a rubber cone-tip blow gun (rubber air nozzle) held into the spark plug hole. And of course keep holding it in position to keep air from coming back out the spark plug hole while listening for escaping air at other places. The air compressor should not be running while listening because the noise will likely drown out any sound of escaping air. Or just use a portable compressed air tank.
Air heard escaping from exhaust port indicates exhaust valve not fully closing (perhaps too tight clearance or damaged valve or valve seat).
Air heard escaping from carb intake indicates intake valve not fully closing (perhaps too tight clearance or damaged valve or valve seat).
Air heard escaping from crankcase breather indicates loss of compression past rings into crankcase (perhaps worn piston rings or cylinders).
Air heard escaping from head gasket area indicates indicates loss of compression past head gasket (perhaps due to a blown head gasket).
A leaking valve may sometimes be resolved by adjusting the clearance to within specs.
A leaking head gasket may sometimes be resolved by torquing the head fasteners when the engine is stone cold (such as after sitting overnight).
Good Fortune!
