Re: [T3] How many miles till rebuild?

<x-charset iso-8859-1>Ill second Russ here, when I did my valve job with around 60K on the heads
there were 2 valves that were starting to burn, #3 exaust was OK but
mishapen and sunken into the head from cheap aftermarket head material.  and
there was ALOT of carbon buildup under the intake valve that was impeding
flow and greatly reducing my low end pickup.

I do almost ALL highway driving, and I think that is harder on the valves.
