Why did you change the head? Then, possibly your timing is 180 degrees out. I know your crank is on bottom, but did you make sure that on cylinder #1 the intake valve opened and then closed, and then the #1 piston came rising up before judging your timing marks? I'm sure you did just that, but back to the first question, why switch heads?

Something is not right here-reverify the valve and ignition timing then let us know your findings
