Do your home work.

I don't see what the big deal is. I run W5's and although they aren't a straight bolt on you can modify things yourself to fit them. Nothing wrong with the M1 intake, I'm using one. I think I could also easily modify a standard intake to fit. As far as the Indy intake, if you get the rectangular port intake it should fit except for the bolt holes. Which should be an easy modification.

I don't know why your W2 rockers won't fit either. I used the same Crane Gold Race units on my W2's and my W5's.
