@Dne007 take a look at my "cheap & nasty" thread. I'm showing how I handle the oil plug timing chain oiler. Feel free to copy it if you so desire. I'm not done with it yet, as I had to order a Holley .040 jet which I did not have. Here's the thread.
Slant 6 timing chain lubrication?

I was wondering how one would drill a .040 hole without breaking a tiny drill bit! This is a great idea~ argh, I wasn't going to do , but now I just may~ ;) 
"So how cheap & nasty is cheap & nasty gonna be? Before I answer that, here's my first mod. See that hole in the middle of the main oil passage plug? It's a little big, ain't it? That's cause it's a beeotch to drill a .040" hole without the bit breaking. So, my solution is to tap it to 1/4 x 32 UNF and screw a Holley .040" main jet into it. Problem solved and the timing chain now has pressurized oil."

I ordered the .040 jet, and luckily, the cam has access to remove it~ how fortunate!!;)
