This isnt a common problem on these motors.Get a head or exchange for a
rebuilt one.I suggest retorque after about 100 miles.Make sure you chase the
head bolt threads and use a good reputable gasket maker (Felpro) Might as
well resurface the head if not already done....Also might want to use new
head bolts or what the hell, get head studs for peace of mind!
