Oil Leak on 1993 Chevrolet Corsica

I have a leak in Head gasket, bell housing, and valve cover gasket wondering how much it would be to fix it.

Asked by for the 1993 Chevrolet Corsica
head gasket pays around 8 hours. this includes the valve cover as it has to be removed to do this repair.
parts are around 200 including the head bolts.
machine shop is about 75.

thanks for using repairpal.
