What are the compresion readings on all of the cylinders????
What are u calling low compression?????
What is spec for optimal compression????

remove all sparking plugs. Knock guts out of 1 plug, thread for hose shank, install hose on shanke and install tool into offending spark plug hole. Bring offending cyl up on tdc and blow air/smoke thru hose to see/hear where it exits engine and reportback.

Did u inspect cam lobes to be sure they were not worn nearly round??????

U sais head was milled. WHY??? How much was it out???

Were the head bolt washers seats spot faced parallel to the new milled surface of the head. I'll go ahead and answer that question now: NOooo!

Do u ahve the OLD head gasket????? Inspect it closely.

FIRST, do the hose routine as outlined above. Watch for smoke and listen for air. Watch for smoke comming from other spark plug holes too. Report back.
