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.
385cfm@800lift - 374 cfm@.700 lift - 364cfm@.600 - 343cfm@500

Camshaft lift is 750 ..

Hoping to make 750-800 -- cubic inch is 474

I bought the heads with a matched victor

True, I am worried about how much I may need to twist up the RPMs

Engine has a cast Eagle 4.250 strk and SCAT H beams
