I got this Evo 9 about 2 months ago. It was sitting for 5-6 years, after a ton of work with wiring, fuel supply and tune I got it running. It runs great no issues so far.

It currently has a BR double pumper setup, FC 1200s, FP 65 Green, Injen piping, and full exhaust. (All these parts are from previous owners, I replaced the old double pumper setup with a new one, and had the existing injectors rebuilt)

I noticed this stamp on the head and have been unable to identify what it is or what shop rebuilt this head.

If anybody can help out, Thank you!
