At what valve lift is that 385 cfm taking place at?
What level of hp are you looking to make ?
How much valve lift are you looking at using?
Depending on if the current valve job done on the heads is maxing out or not at the OD of that 2.250” valve, you may be able to switch over to a safer size 2.19” valve with minor seat work for now.
Also note that to make good use of even 350 cfm no less 385 is going to require a ported Victor , or a BOP intake or such, and a BOP has too much runner area for a .060” over 455 unless it’s built go to 7800 or more.
