For 8-10 hours,he must be adding time to repair the exhaust studs he breaks off,when removing them.

By the sound of it, you seem to think it's his fault if they break ??

Why so??

Edit - Actually,, I just reread your post, and perhaps took it wrong..

My Flat rate book shows 1964 - 67 - 2.5hrs.... 68 - 72 - 3hrs..

or 4.4 and 4.8 if you adjust valves,, which you gotta do anyway imho..

Shoot.. book say 6.8 and 7.2 hrs to do a valve grind including tune-up..
