just a few thing you might like to consider when your doing the head gaskit 1. dont tip your carbie upside down when you have it off. 2. use a bit of copper gresse on exhust studs (it makes it easyer to take them off next time) 3.when tensioning the head start in the middle and work your way out from there one at a time and keep swaping sides 4.keep checking all the rods are in the rocker arms.(while you have the head off check the rods by rolling them on a peice of glass if they are not spot on find some that are)5.dont over tighten the rocket cover you may need to panel beat it first to make sure the gasket surface is flat. it is a good idea to get the head skimed it dosent cost much,imagine doing all that work then having to do it all again because you wanted to save a few bucks.hope the info helps. chris
