Im new to the v6's and kind of screwed up when installing my heads, I didnt realize that i needed sealant on the head bolts till after i had installed and talked to a buddy My question is first what sealant should i use on the head bolts(not studs) and second can i take the head off to clean the moly out of the holes and off the bolts and still use the head gaskets again ( cometics) or would i be better to take one bolt at a time out and try to clean out with the heads on.Not sure if i screwed myself in regards to the head gaskets but figured i would ask for some input here. Thanks for any input you can give me.
