What plugs to run in TA aluminum heads

Hey, sorry if this is a repeat post.
I have a set of TA aluminum heads and the only options for plugs according to TA’s website are the NGK BP#ES which I can only get a 0.028 - 0.035 inch gap. I’m running HEI and looking to get at least a .045” gap.

What if any are the other options to get a larger gapped plug with these heads?

 

I use FR-5.

 

I’m running the Stage 1 TA heads, MSD HEI around 10.5:1 compression.

I’m seeing FR5’s or NGK 7373’s as the go to.

I was running BP7ES and needing to go with a hotter and larger gap NGK.

Thanks!

 

I'm running autolite 52's. Crosses to ngk bp7es. Think they run cleaner than the ngk's.
