Nowadays, you have a lot better technology going into the parts and single roller timing sets for LS engines are a lot more precise and rigid than even double rollers of yesteryear! (Yes, I said yesteryear!)

If you are going to be spinning 9,000rpms or better, just go all the way and use a timing belt system because the accuracy and rotating mass cannot be beat at those RPMs...
