  • Fast shipping received one bad head
One of the cylinder heads has dents and dings on all the sealing surfaces. Alsow the heads were painted silver witch was over the dents and dings

  • Waste of money better off rebuilding what you already have.
Lasted about 10 miles after finished putting the motor together and putting it in the truck. Had to take them to a machine shop and have them completely redone costing me another $650 so now I have about $1300 in the supposed “new reman” heads

  • Could be better finish
Had bad bolt treads on exhaust and valve cover. Over all looks good and they are working. Fully clean.

  • DO NOT PUTCHASE ANYTHING FROM THIS COMPANY
You will be sold beat up heads that claimed to have went through a vaccum test and a valve job. All they do is paint all sealing surfaces with an enamel to hide cracks and will not seal or hold vacum
