Head came back looking good.
Is the distributor right? Don't know how your kstar is set but my distributor is retarded about 6 degrees, the kstar then compensates for this (when it was working anyway!)
Check the obvious, sensors etc all plugged in, getting a good spark, etc etc. The cars been sat for a while hasn't it?
When I rebuilt my engine, my car wouldn't start either, it was turning over but not firing. The starter was a bit slow so I bought a new Lucas one, it now turns over alot quicker and starts on the button....
