SBC Vortec Plugs?
#3
I used the factory GM Delco plugs for a '97 Tahoe. I bought marine plugs from BoatUS a while back for my old heads and then was promptly beat the crap out of by one of my old offshore fishing buddies. He basically said that I was paying an extra $3 per plug for the "M" designation and that if I ever bought plugs like that again he'd take my boat out and burn it to the waterline!
I don't use marine plugs anymore... never will. For what it's worth, the projected nose Tahoe plugs worked just fine.
