lol... head bolts was a deceiving title! If your head bolts are loose, you really would be in trouble!
I hope your talking about just the valve cover bolts? Use some black RTV sealant on the valve cover gasket and put some on the threads of the bolts. Tighten them down good. Then retighten them again in like 50 miles or so. After, they should'nt come loose again.
