Vette alum heads... What sparkies to run?
I plan to use Delcos, but I noticed that a corvette L98 calls for something like a FR5LS while a camaro L98 gets a CR45TS. Which one should I use with my vette heads? I was planning on using the plugs recommended for the vette. Advice?

My ZZ4 motor came with MR43LTS. I am currently running R44LTS AC Delcos.

There is a different number because Corvette aluminum L98 heads are different than Camaro/Firebird iron L98 heads. If you're using the Corvette heads, use spark plugs recommended for them.
