I'll be putting the head back on my 80 tomorrow, and am thinking of using a head gasket sealant just for insurance. The head's flat, the block's flat but there is a slight texture here and there on the block sealing surface from the old gasket after cleaning. The machine shop doing the head work (cracked head) tells me that a quality anaerobic sealant such as "Gasket Cinch" or NAPA's house brand is excellent, but they would not use anything else such as "The Right Stuff" which is silicone base. They say it won't harm anything and can only help longevity.
They tell me there is no need, but I'd like to use something as assurance. What do you guys think? What would you use? I'm using a factory Toyota gasket - metal laminate with a clear slightly gummy layer that actually contacts the head/block sealing surfaces.
