Default Engine Smokes

Okay,

I have a 90 miata with a 302. The engine was rebuilt before installing, ordered aluminum heads pre-assembled springs and valves. I chose to use an edelbrock intake and 600 carburetor.

The right bank at idle smokes out the tailpipe. When I hit the gas, the smoke stops. Any Ideas as to what would be causing this?

Wrong ring gap , rings upside down, rings not seated , valve guide bad , valve seal bad Pick one?

Also pcv system may be sucking oil in some bizarre way.

Working PCV system ? If pcv system is all good I would bet money on valve guides or possibly a cracked head. Any power loss issues ?
