distributor is set right, firing order is good, the engine ran before it was installed, all i did was put 305 heads on it and a new carb, but every thing was drained from it and nothing other than the heads were touched. and intake were touched. the engine was rebuilt once before, but had been run since. what am i missing?

What are you missing?? From the way you descripe your problem it sounds like you have either miss timed the motor, or dropped the dizzy in and missed the timing that way. If the engine ran before and you have done only the things you mention it will run again. Don't "ASSUME" the dizzy is correct. Check it! Dont "ASSUME" it has the correct firing order. Check it! If you have already checked those things and it seems correct- Do it again. the problem is in the timing some way some how, I just bet.

Head swap, did you check for proper push rod length? Did you adjust the valve lash? What about rockers, are they properly adjusted? Could a head gasket slipped while installing? Then again, did you torque down the head bolts properly and in the correct order? New head bolts? Way too many things come to mind that could go wrong just with the head swap. I'd still double check the distributor as the first thing, then work your way down my list.
