Could be a LOT of things -
- Your Timing may be way off? (what's it at with any vacuum advance unplugged & plugged in?
- Vacuum advance not connected to the proper port (if you're running it)
- Vacuum leak on manifold or base of carb...
- Cam timing off or jumped a tooth.
- Firing order not matching cam...
- Valve lash set way too tight hanging a valve open.

Start with the basics and re-check everything one at a time.
