What kind of plugs does everyone like on their SBC with Vortec heads...I like the Rapid fire's but I don't think they make one for the Vortec Heads.....

I am planning on running the projected nose Ac Delco marine plugs #MR43LTS..

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.
