Harley Heads

Here is where we will give you an inside peak into past projects we have worked on. Chuck likes to keep things
​moving through the shop, so if you do not see any updates on your items, they are probably ready for pickup.

Honda Rebuild

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. 

Diesel Heads​​

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.
