Re: heads still leaking

Don't use any sealant unless recommended by the manufacturer on the head gasket. I would suggest removing the head (you have to anyway) and take the head to a machine shop and have the mating surface decked 0.005 inches. Shouldn't cost more than $25-30. It sounds you me like you have a warped head (often the result of overheating). Make sure when you install the new gasket that you not only torque the bolts to the right torque but in the proper sequence (see manual).<br /><br />PS ixnay on the Bweldjay.
