Gaskets are pieces of polycarbonate. Or aluminum material that is used to seal up air, fuel, coolant, or oil lines in a car. AIr in take WILL NOT CAUSE SMOKE. An oil seal in the cylinder head will cause smoke. If you choose to replace your head gasket. GO to A DEALERSHIP. Mom and Pop repair shops do shity work and take to long and do not have the right skills to preform the job. I replaced my Intake and Exhuast vavles and had the same problem. The situation was my Valve cover need a new rubber seal to prevent Positive Crankcase gases from escaping the valve area of my engine. Number 2 the reason your valve cover is immitting smoke is due to bad timming belt. Exhaust valves are not opening fast enough to allow exhaust to be released into the exhaust manifold.
I own a GST eclipse and I work at a auto parts store here in Seattle WA.
