OK, I ended up getting the cap screws from Lowe's to replace the ones I got from Chrysler that were too large. Tonight, I've applied the sealer and reset the covers; set the bolts and reconnected the ignition coils. Tomorrow, I'll reconnect the hoses that I removed and give it a quick run to see how I did. Crossing my fingers, but I'm feeling fairly confident that I did everything correctly as I've researched this process quite thoroughly.
Thanks for everyone's input. It's much appreciated.
