It does sound like a fuel issue but since you installed the head it could be a wiring issue. I agree you should ck to see if your getting fuel pressure.
Also loosen the distributor and turn it all the way advanced, which is turning it all the way clockwise.
You can also spray a little carb cleaner into intake to see if it tries to fire. Just make sure its flammable carb cleaner. If it doesnt fire then I would look into spark.
