jbooker82 Posted June 29, 2009 Report Share Posted June 29, 2009 Coat the o rings with some vasoline or petrolium jelly. Don't use grease. Vasoline will melth the first time you start it up. Regular grease won't and it could plug the radiator up. Unbolt the rear elbow fitting on the back of the head instead of undoing the hose clamp. That way when you go to reinstall the head your not fighting the rear hosen while trying to keep o rings in place. I install my prodesign head one piece at a time. Set a dome over each cylinder then slide the shell down on top of the domes. That might be a little tricky if you have a one piece noss, or chariot head. Tighten it down. Then bolt the elbow back on the rear of the head. Don't forget teflon tape or other thread sealer if those bolt holes go clear into the head.
