"fit " and "safely fit " are 2 different animals yo ucan get a 28pwk to fit up using all your stock stuff pretty easy wit ha few tricks yo ucan make a 34mm keihin fit sometimes it prematurely causes them to crack if your using sotkc intakes though best to get a real oversized intake manifold its only like 60 bucks
