Can I use LS1 spark plugs in my RS??
My 1991 RS needs some new plugs, and I have an extra set for my Trans Am, I was wondering if they would work in an L03. Anyone know?? Thanks. BTW the plugs are AC Delco.

I'd seriously doubt it. The ones in your LO3 are tapered seat, the ones in the LS1 are most likely a gasket seat... I havent changed plugs on one yet so I'm not sure 
All the aluminum heads I have seen use gasket seats, and those dont work on tapered seat heads.
