I think Edelbrock recommends an Autolite 3925 for my heads. I've been running a 3923, which is 2 heat ranges colder. Is this too cold? Could I jump up to a 3924 maybe?

I'm putting together a new 306. Compression is around 9:1, 93 octane pump gas, 10 psi, and I'm most likely gonna use a AFM blower cam
