I know this will be engine and head dependent, but is there much to gain by stepping up to 2.15" intake valves versus 2.09?
Engine is a stroked 428 with ported CJ heads in my 69 Mustang that is street use, so nothing radical as far as cam.
I was going to go with MR heads and headers due to piston constraints (11.5 to 1 with 72cc head) already installed, but rethinking...
