I see out of everything you listed that you changed you didnt list the coil. Did you replace this as well? If not what does the spark look like? Is a cool blue spark or a hot red spark.

The reason I ask is a buddy of mine was having similer problems on a carbed 305 and after replacing everything, turns out it was just the coil.

Inside the distributor cap there is something called a I.C.M ?? I think ? 3wires on one side 4 on the other side ?? kinda shaped like a. boomerang

tried the coil didn't do nothing to help me and I did change that piece in the distributor didn't help im thinking bad set of injectors maybe im retesting the fuel presser tomorrow at work just to make sure before I go any more crazy with this car..

Check the coolant temp sensor... if it's not telling the ECM the engine is warmed up, it could be hard to start when it's hot, due to the A/F mixture being too rich.

ok it ended up being the intake gasket was leaking fixed that runs great now but for some reason now it ha a valve tap when I didn't touch them I know for a fact nothing got stuck in my lifters cuse I vacuumed it all out and had it covered really good runs like **** a lil when tap goes away runs strong with the tap. so lost on this one...
