Found this over at LS1tech.com and thought you guys might like it. Looks pretty darn good to me! Car had used Mobil 1 for it's life.
Quote from actual owner........
I installed my new heads/cam/intake this weekend and when I pulled the heads off I was surprised to see that you could still see the original crosshatching in the cylinder sleeves.
My car has 78,000 miles on it and has pratically lived at 6k RPM. I am very pleased. I have pulled cams outs of cars that use regular non synthetic oil and after 5k miles it looks worn.
