Your call. When you swap up to a larger cam, have the first set reprofiled and see if they're still just as large as when you put them in.

 

As a matter of fact, I recently did this to quell rumors about the regrinds going bad. The bottom line was there was no unusual wear or change in profile. The cams I have in my car are over 5 yrs old and have been run rather hard as you can imagine. I do apreciate your advice, but I have not had a problem with any of the web cams I have run to date in any of my cars. Don't just listen to heresay, find out yourself. I also have a set of regrinds in my Porsche 911 as well with out any signs of unusual wear.
