the team g is a good intake on the rest just sounds like a nother bbc build no big deal if you machinist is working over the cam numbers there not much i can help you with like said over ported stuff you have to watch out for it could be a pig 427 reworking the intake runners is a big no no only a good bowl job and a 4 angle seat job is all you need and on the ex side full radius cutter and bowl work and some small port work less you have flow numbers to back up the all the work. sorry but you could have over work junk. bigger is not allways better on the intake or EX the short side radius is ok if someone took the very small amont that is there they will flow poor on the ex side
