You need stud mount rockers for the new heads, which means you need the trick flow valve covers to clear the rockers, which means you need the 3/8" intake spacer for the egr and IAC to clear the VC's.
I would get some sort of tuner for the car and keep the stock maf, or get a PMAS cal'ed for whatever injectors you choose (30's are perfect IMO).
Definately get some non-EL shorties while you are in there. I love my BBK's solid flange design and weld quality.
