I have a new to me 2010 TL, love the car but started making the dreaded valve train noise. I opened it up today planing on doing a valve adjustment and found a lost motion spring broken and one of the rollers on the rocker arm pretty well destroyed. So I am just planing on putting cams in both heads, all new rockers and all new springs. I don't feel that I need to change valve springs, but will change all the springs in the rocker system. I want OE Factory New cams and have heard that RL cams provide more low end torque and pull all harder all the way to redline. Does anyone have first hand experience with using RL cams? I am perfectly happy with the TL and the power it has and the way it runs, I would be happy with the TL cams. Just figured if I am doing this job then now is the time to make changes if need be. Are there any other things I should consider doing while I am in there doing this job? Obviously I will be doing a timing belt and all associated parts. Also, If the RL cams are used does this require tuning after they are installed? I am planning on adding the RV6 High Flow Cats and XCLR8 J-Pipe as well. Any guidance would be greatly appreciated. Any suggestions for the best pricing on OE Factory New parts would be appreciated as well.

Thanks A Bunch!!!
