I got the head reinstalled, I lubed the bolts as I was told, but Im curious if any of the bolts needed sealant, do any go into a "water jacket" I was unable to tell on the left side of the engine, should I pull and use silicone permatex on those or not?<br /><br />also<br /><br />Ive misplaced the nut that retains the prop.<br /><br />where can I get a replacement?<br /><br />thanks
