Aftermarket heads are mass produced, this leads to valve seats that are cut rather quickly. For the regular rider, this is just fine, but for those who seak to have a nice seal in the chamber and that little bit extra a valve job is a must. These brand new heads came in and were machined with a 2-angle valve job.

This is a 5.9L Cummins diesel head from a homegrown tractor pulling good guy who needed a quick skim off the top to make a good gasket seal. This is a common thing here at Exton's during the off-season of tractor pulling. Feel free to bring your head down so Chuck can put a straight edge and check to see if you have a good seal before you hook up to the trailer or sled.
