Get those heads/pistons/cylinders/valves cleaned up I will get you the hone wednesday. I expect you will have all this done asap. Order your cam wheels as you cant reassemble it without them.
getting those pistons back in will be a pita. I can loan you the porting kit it makes cleaning the ports on the heads a 5 minute deal with the die grinder and the fluff wheels. I also have some long brushes you can use to clean out the fins before you spray.
