The stop leak and the warped intake are signs that the truck has been overheated before, and this recent overheating didn't help. You shouldn't need RTV to seal the upper intake. You may have a cracked head or blown head gasket. Pull out the spark plugs and check the condition of them. They should all look relatively similiar, but if coolant or water (whichever you use) is entering the combustion chamber then one or two will be either cleaner than the others or it will have chalky white residue on it.
I havent had it for long but it did sit for a few years
Exhaust is a true dual and the truck ran fine before I put the valve cover on it
When I took the upper intake off this time I noticed it had been welded where the back drivers side bolt goes through so it wasnt sealing
I started it yesterday and I think its OK now but couldnt tell cause of the condensation but it did run better
When I replaced the plugs they looked fine so I dont think it is warped cracked etc but you are right it cold be block sealant
I will see if it ever quits raining
