Magnum reseal questions?..

Day 3 and I'm finally seeing light at the end of the tunnel... Let's just hope it's not the train coming the other way to run me over! LOL...
I took the spark plug wires off then change the plugs and they were Auto lights that looked like they were colder than the stock plugs. I got the stock champions are called for.. that was a good choice the plugs were shot.. also changed the cap and rotor and they were for all intent and purposes shot as well..
I pulled the valve covers and got them cleaned up and also got all the surfaces on the engine prepped... I gave the keg and take a first cleaning.. it will still need a gasket scrape and find cleaning around the injectors.. I'm going to go ahead and get a little O ring gaskets for the injectors as the lower ones all seen hard.. upper radiator hose thermostat and valve cover gaskets.. I'm pretty sure they were all original..
