Since O'rielly bought out Kragen you (and esp. their employees) get screwed. There is no reason this should not be a stock item. There are 300 trillion vehicles out there with these plugs. You have the same disadvantage as I living near small cities with limited stock , but there's still no excuse for these not to be a stock item.
When you take the valve train off that means the timing belt will need to be adjusted again. (The good thing is eventually you'll be able to do a timing belt job with your eyes closed, which at this point your probably already there).
A thin piece of plywood and possibly a brake adjusting tool might get the the angle for pressing them in. An ice pick or good seal pick set , too, (don't slip and scratch anything).
Do this in complete darkness,,,use a focused flashlight to spot the cam plugs from under the truck. You can squirm around under and get an angle and you can see them. "Polishing hard" with a rag is really the only way to clean back there. Powder is gonna be impossible to get on that upsidedownish surface and your gonna make a mess. (I've used power on the engine on oil pump gasket checks and it works good). I used UV oil dye and a black light. But with the air from the fan , etc. the dye migrates pretty soon and isn't that usefull either.
My engine drips , too.
I'm don't think Felpro v.c. gaskets have the nice little tabs on them ( maybe those without are Victor Rienze from NAPA and Carqueest).
I have bought those plug at a stealership for like $5 ea.. As metioned before the price at a dealer can vary 500% from one side of the county to another.
