Carbruator issues / timing
I replaced the cylinder head on my 300 six . I got valves set about right . The carburetor is spitting badly and I can't seem to get the ignition timing corrected . Do I need to pull the distributor and move the rotor so a cylinder will line up correctly or what ?

I have done that ! Remember now , that Ford 6 has timing marks , ONE IS INCORRECT on the Timing gear cover .
I have pulled the distributor until my feet could NO LONGER support me . it either starts with too much advance , spitting THROUGH the carburetor or , wont start at all !!!!!!!!
I'm convinced one can NOT try and time this truck on TDC or piston 1 !

Here is where I began to inspect the two sets of timing marks . I used to TINY notch on the Crank to TDC on the "Sawtooth " marks on the pass side . I poked a screw driver to determine if the piston was indeed UP!
The Rotor was pointing at #1 . The motor would only start and run , ( Through spitting the carb ) in an EXTREME advanced position . I have tried backing the timing by moving the distributor back ONE notch in the RETARD . This has done NOTHING . problem is I have NO One to help and I have no way to get parts now . This was my driver !!!!!!!!!!!!!!!!!!!
Oh the engine is a 1978 Ford 300 4.9 L VERY stock engine 890000 on the clock

OK , to start at the beginning , I replaced the carburetor only to discover that #1 piston wasn't doing it's job . The Piston appeared to be OK but the head had a bad valve . I replaced the head with a USED head . It started initially and I began to re set the valves . It rattled and I let out the clutch to stop the engine cold .

I again suggest you check for vacuum leaks. The symptoms you describe are almost identical to what I went through after installing a new engine and having a massive vacuum leak at the gasket face.
Remove the brake booster hose from the intake and attach a long enough piece of hose the same size to the intake, so you can comfortably stand/move around the engine with the other end of the hose in your mouth. Get a cigar and gently blow smoke into the intake through the hose for a minute or two. Good lighting will obviously help you see any smoke that leaks out around the engine.
I'll bet you have a nasty leak somewhere.
