'88 tappered plug or not?

I'm having trouble picking up the right plug. Some of the plug books list a tappered plug and some don't.

Well, if you're using ACDelco..my favorite, the plug number is 41-629. You can also visti their web site.

Is that a tappered plug? Or normal, with the washer?

I've got a '90, L98 with aluminum heads and the spark plug specs are as follows. 5/8" hex, 14MM thread, 3/4" reach, std gasket seat, the AC spark plugs use a projected tip. The cast iron heads are using the same spec accept for the reach, which 0.706". Check out www.sparkplugs.com. Very good site.

Looks like my car needs the gasket, non tappered style. Ok!

You are correct. I had trouble finding plugs for my 88, nobody had them. They kept trying to sell me the short ones for the cast iron heads. I had the Chevy dealer order me a set of Delco's. I never go there for parts, it was weird.
