And your exhaust side is separate so nothing will go from there over to intake side except back through the exhaust valve but highly unlikely.
What about the glow plugs? still got end on it?
Check intake/exhaust valves in case bit broke off and you not noticed yet.
A good eyeball of everything will help.
In my case I put head back on after removing ball bearing (years and years ago) and it ran fine till it went to the wreckers.
