I have a pair of BB2 plus with major port work.It has 2.25 intake valves in it.Im not home but only remember the intake flow # @.700 and it is 379 with 28.What difference would I see if I put 2.30 valves in it?Reason I'm askin is I'm gonna build a 555 and currently have them on a 482:D

i guess this is the wrong site to ask

Yeah, head over to the DRR site, check in on the Bracket Talk forum and ask there. I'm sure there's someone over there that can help.
