Default Re: head replaced SECOND TIME

I think that earlier post about driving it hard hits the nail on the head. They didn't have as many problems with the I 5 on the Canyon trucks and work trucks are always overloaded and abused. My early VIN H3, now in the hands of my son in Denver is still going strong, but I did a lot of towing of my bass boat with it, hard driving, and mountain driving with the pedal to the floorboard. 90,200 miles and no problems - I'm not sure how that helps the head, valves or valve seats, but it's worked so far.
