Engine: 88' V6 200hp<br /><br />While I have the heads off should I do anything else (besides replacing the head gaskets).<br /><br />Should I use some quicksilver perfect seal or other product between mating surfaces and the head gasket?<br /><br />What type of sealant should I use for the head bolts? I was thinking 2-4C grease.<br /><br />Thanks
