Spark plugs for BBM heads

I paln to CC my BBM heads but then realized they use a smaller spark plug than the one in the stock heads.
So what plugs shold i be getting for track use.
And I just realized the plugs I've been saving (including a a set or two of Holley spark plugs) will be of no use to me - lol.

I run the NGK BKR6E seems to work well for me with 11.3/1 CR

Compression ratio is unknown, that's why I'm ccing the heads. I'm guessing 10.5, hoping for 11.5, would be delighted with 12.5.

The plug will depend on the compression ratio. I run 10-11 on Autolite 3323’s and 3324’s. Higher than that, I usually switch to a colder plug, like a 3910 or similar.
