Yes you can, only prob may be mapping the ECM for the difference in vacuum at idle from the different cam profile. Try and get it set up with an mefi 4 ECM.

i have the proper cams and ECM's that were custom mapped by Tyler Crockett for this set up. I just wondered if technically there were any differences in intake/head mating faces or anything like that
