I've been reading about the rebuild prosess and there is mention about upgrading the exhaust valve seats or exhaust valves to cope with todays unleaded fuels. Typically my truck only gets out on weekends with around 50 to 100 miles put on it in a weekend if that much.
With this type of driving, do I need to upgrade the valves or seats?
Thanks
Rick......... | | |
