1989 Jeep Cherokee Engine cranks but will not start for

The problem:
Hard starting after sitting and cooling
1. Replaced HEI distributer assembly
2. Installed OEM spark plugs set at.045
3. Installed new 9mm plug wires
4. Installed rotor and cap
5. Head gasket changed after being blown but head and block were not warped as.001 feeler gauge cold not pass through with a machinest straight edge and marble block
In the morning the engine is hard starting thought the battery is good and less than 6 months old
after starting the engine runs smooth with no hick ups.
after cooling for about 6+ hours it is some times hard to start.
When warm starts 2nd or 3rd crank.
I would like some better guidance than the haynes book gives me.
