This is for cylinder head work on your 5.9 or 6.7 cummins head you send us. We do 12v & 24v. The head will be cleaned inspected and if any parts need replaced we will tell you. Then the head will get extensive porting on the intake and exhaust, the exhaust will get polished also this isnt just a sanding roll clean up we remove metal and we remove it at the proper places to improve the flow, swirl, and keep velocity of the air up, we usually have 30-50 hrs in building a head. The head porting basically increases the airflow of the cylinder head so your engine can produce more power. If you would like any oversized valves, upgraded valve springs, push rods, we have many options to give you what you want. Also offer other machine work like surfacing , O ringing, maching the intake off so the head can then be fully ported, spring seat maching for custom valve springs, also block work can be done. If by chance you would want to buy a brand new head fully built we also offer that. Any questions feel free to ask Thanks for looking. 724-875-0764 /font>
