"I want to do a compression test on my engine, a 5.7L MIE, and the compression gauge that I own only has adapters for straight, not tapered plugs. Does anyone know off the top of their heads if there is an adapter available, i.e. straight to tapered, or do I need to buy a whole new gauge?"

"Whew! That was too close! LOL. Thanks, Wrench. I'm so old that I remember Sparkplugs that needed a 7/8 Socket. (26 Chevy). Tappered Plugs? Had me stumped! Thanks, Al W."
