Order #1469038 Unfinished Product
#1 injector feed tube port was not drilled all the way through. Injector bore depth different from original head. During install of valvetrain one of the rocker hold down holes stripped all the threads out at only half torque spec. Quality control must be non-existent. Ultimately had to purchase a different head from a different manufacture due to down time of my customer.
Had to switch a exhaust valve and Intake valve around as they were in the wrong spots, 2 ports were tapped with the wrong thread pitch, ones for map and boost sensors to be exact. I'll write another once I run the truck.
Received cylinder head still had mill turnings in it.intake cup had steps in them from bad mold had to have them all ground out.

Questions and Answers

Does this head come with aftermarket valves and springs or are they stock replacements?
View Staff Answer 

The valves and springs are stock replacements.

Is this head a direct replacement or will I need any custom parts to do the job? My 1999 dodge 24v truck is leaking anti-freeze, but not to the outside of the engine, or into the oil. The only other place I could figure was into the exhaust. A mechanic told me that they are prone to cracking around the valves and doing that.
