figured i would post up the templates i found. these are for if you wanna try grinding your own fuel plate on a 12 valve cummins. everything i've read says get an extra fuel plate and keep grinding starting with the most mild and go till you get the desired result without toastin your engine. you can always take more away but you cant add it back. also after the grind you wanna leave enough metal so that you still have room to polish the edge down to a smooth almost mirror like surface.
i have not done this but i spent about 2 weeks maybe more reading everything i could find on it
