I just pulled all 4 heads (twins). Cylinders look good as do piston heads. Apart from breaking one of the thermostat leads, it went pretty smooth. <br /><br />I plan to run heads over some sand paper (220) to ensure they are fair.<br /><br />Should I install the gaskets dry, or use some sealant? I've also heard just to coat them w/ some motor oil.<br /><br />What should I coat the screws w/ before re-installing, if anything?<br /><br />Anything else I should be doing/checking w/ the heads off?
