Im looking into doing A LOT of head work on my head and i am wondering if anyone has done over sized valves on their CR head?? If so who did the work for you and how long have you been running this modification?? I have had this on other high end engines of mine and I would like to do it n my CR head while im at it. Any info would be greatly appreciated. Thanks, -JD

 

it's highly recommended to do oversized seats if you plan on head work. CR seats are known to drop easily.

Scheid Diesel or Haisley Machine is who I'd recommend doing it for you.

 

What year is truck? 04.5+ truck had a better head too
