Will the 3.8RS cams work with a 3.6 engine?
A s far as I know, I have looked at several cars that purport to have them

How about emmisions (since we have some of the toughest testing here in Canada)? You also have one Cam, are they $900 each or for both?
Emissions I havn't a clue about, WAG they are ok. That was for the set from WebCam, new billet only available w/ the old style drives.

Are the RS valves larger? And if so I guess you have to either replace the heads or change the seats on the exising heads.
Yes, by 1.5 mm yes, new seats, valve job and guides were being done anyway. The valves were the expensive apart @ $100/ea.

I have not heard of "Competition" timing chains. The pricing appears to be the same as "normal" chains...
I was told that there were 2 grades of endless chain, I went w/ the upgrade. I don't believe that they are a normal 993 part, no faster just supposed to be more dureable
