Aluminum cylinder head guide

[abdywgn]

in the Summer 2013 issue of EngineMasters. Steve Dulcich does a nice,simple job of describing whats offered and power expectations.No W9 heads but Indy has 3 head offerings.Didn't know they had a T/A type cylinder head available. All in all, good article. Bob

The W9 is considered a exotic head. A real race part. That is why it is probably not in there.
They do have listed somewhere about a standard block W9 head.
