Oil leak on passenger side head below cam pulley.Least expensive way to fix? on 2001 Audi Allroad Quattro

All engine seals have been replaced, including cam. Tech tells me I have to buy a new head. I want to find a less expensive way to fix it. They tried putting JB Weld on the outside, front of the head, but it didn't stop the leak.
