It depends on what type of gasket you use. If it's a composition style, no sealer. If it's the steel shim type, spray it with Copper Kote. Opinions vary for sealant on bolts, but I always do it on every head bolt I touch, whether they go into water, or they are blind holes. Keeps them from seizing up if you ever have to remove them and affects torque very, very little. I always use red high tempo RTV. Sorry, I cannot help with the bolt torque. What's the thread size and do they screw into iron or aluminum?
