Heads and Cam notes from the 2011 parts catalog

So I took a look through the 2011 parts catalog and searched for MBR and M50BR as these are the parts listed for the 302R and seem to be the Boss specific parts. Here are the items that stood out to me:

1. the exhaust valves are 31.8MM vs 31MM in the GT and are sodium filled

2. the intake valves are hollow stem but are the same diameter as in the GT

3. the heads are listed with a 4% increase in intake flow but nothing is mentioned about the exhaust side

4. only an exhaust cam is listed and the lift is 13MM vs 11MM - will the intake cam be the same as the GT? On another note I went back to the spec sheet which lists the valve diameter and lift as being the same as the GT....maybe overlooked on the spec sheet?
Nice, do you have a link to the catalog and a price list? I'd like to find out how much the LS wheels in black are going to cost.

note - there are no prices listed for the Boss stuff
