All i have to say is good luck. I just did this a couple months ago and it was a huge PITA. lol. Remeber to replace all the torque to yeild bolts. I used permatex spray on my lower intake gaskets. And i used copper spray on my head gaskets, but mine were metal. Use a dab of RTV where the lower intake gaskets meet. umm If you port and polish your heads, you should repace the valve seals cause all the stuff you grind off will go in there. And pretty much if you take your heads apart you should replace your valve seals for good measure. I dunno hope that info is usefull.
