Default runnin the valves

I was talking to one of my buddies and he was sayin that if you run all your valves down a half turn that you will make a lot more power in a way i can belive it but also will it f*** up my head?

There is a probability that your pistons will hit your valves, and they may stay open all the time without the proper lash. I strongly do not advise that adjustment.

if you have stiff springs, cam and lifter wear become an issue as well

I have done mine at 72,000 but I put some injectors in my truck.I did a truck(2002)
that had 112,000 on it and the valve lash was good.Between 80 to 100,000 a good time to check.Do you know how check for proper valve adjustment.

Turbo 20psi, I inherated the truck with 189k so I don't know about the valves. The owner [my best buddy] was a professional trucker so who knows.

Good time to go ahead and check them,it wont hurt.Some of the guys have adjusted there valves and the truck was more responsive and less noisey.


Detailed site Valve Lash Adjustment
