92 Cherokee 4.0 takes forever to start on a warm/hot day

I have a 92 Cherokee laredo that turns over and over and over and over before finally starting on a warm/hot day but if its a cold morning and it'll start right up most of the time..I replaced the ignition coil, new plugs, wires, cap and rotor, replaced the head gasket, intake and exhaust gasket, valve cover gasket, change the oil and filter, cleaned the throttle body and seafoamed it hoping something I did would make it fire up easier and quicker but had no luck. Ideas?

Heat soak, search it. The under hood heat makes it vapor lock sort of.

90 - xj laredo- 4.5" rough country lift, 6.5" of total lift with drop brackets, zj disc brakes on c8.25, olympic winch bumper, jcr upper and lower quarter armor, IRO hack-n-tap and rock sliders and rear bumper. rugged ridge 8500lb winch. Spartan locker up front. With a jd yellow paint job, 97+ front end and bushwacker cut out flares. 35's

I also forgot to mention when its hot and sitting for awhile and it finally starts up a blue cloud of smoke blows out my side pipe. Could I maybe not have enough back pressure in the exhaust? I'm running it with no Cat. but am running a glasspack with a 4" out the side.
