would you put a new set of heads on a 120,000 mile engine. same comp ratio. just new afr's or somthing.

I did it on my 113,000 miles engine. Most guys in here with good h/c/i combos have the stock 100k+ motor.

 

[BlackVert]

yeah, but i'd do the lower intake too. the intake is the #1 biggest air-flow restriction on our motors.

If your not sure, do a compression test. Mine had 70,000 when I did the heads. And You could still see the cross hatch marks in the cyclinder walls.

Yep, do a compression test (wet and dry being important) and then go for it if it looks good.
