Curious about others 421 cub set up

[Methfireroad]

I have a 421 4mil cub that I'm running pump gas on. It's fully drag ported running 35mm pwk that are tupered to 37s I'm running B9ES. I'm running 152 mains and 48 pilots. Around 1000 above sea level

I'm running on race fuel, drag ported with 35 pwk's 158 mains and 48 pilots with CEL needles, B8ES plugs. Around 900ft. I haven't had much time to tune it yet though.

[Methfireroad]

I'm pretty sure they are CEL. And I'm running the the b9 because my builder said I should run them and they r a cooler plug. Wanted to see if some other people where in the same range

Most run 8s for gas & 9s for alky.
