I have been hearing about these piston to valve issues lately. My guess is that the Romeo motors must have flat top pistons or something. Here is one guy that had issues with those cams.187import said:I have a 03 with all the bolt-ons, tremec trany,4.10's,full exhust. What cam would you recommend? I'm thinking Comp Cams xe270ah? But heard there was valve clearance problems? Any info or sound clips would greatly appreciated!
