As I said, the Burb had about 40K on it when I sold it.
I am not real happy about the fact that the castings are likely made in China Butttt.
Clearwater claims they machine the casting in their own shops.
I look at it this way. If Frito is going to buy them and run them in their delivery rigs there is something to be said about that.
I have yet to hear any substantiated issues with the CCH heads.
I have heard the usual unfounded drivel, but nothing substantive as far as problems either short or long term.
To say it again, I would buy another set/sets again in a heart beat.
The Old GM stuff was/is marginal at best.
Now if you wallet floweth over with $$$$$$$$$ the AMG stuff is really sweet.
I would not doub't anything that AMG makes.
AMG/GEP has done a fine job with redesigning the 6.5 to make it a worthy engine with a good future.
