Sorry, could you run by what else is done to this motor also along with the jun cams? Just as a reference.

The Production class rules are fairly restrictive to the newer cars like ours, but we can still open it up a little: intake/exhaust ports opened up to match intake/header to a depth of 1". Multi angle valve job. Head decked to get us closer to our 11-1 max compression ratio.
