I run NGK UR5's on my street truck (468) and Champion Race plugs (can't remember the number) in the 396 for the track. Also, the Bosch Super's from Autozone work surprisingly well. MSD now has a line of wires out that are considerably cheaper ($45 or so a set-build your own wires). I'm running those on my 468 with now problems. Sounds like a compression check is due of the engine has a bunch of blow by. It could be rings, but Big Block Chevy have a bad habit of chewing Valve Guides which will make it use oil and have low compression.
