I have a 165st engine and the repair manual I have says to use a sealant on both sides of head gasket. I have always installed the gasket without any kind of sealant. I’m wondering what other people do?
I’ve used the Indian head shellac on the case halves before but maybe I’ll give it a try on the head gasket. I’m using a Webco head and it seems to blow past the head gasket I have on now without any sealant.
