Got some new 190's and they came with .060 washers on them. Also got an install kit that has .025, .065, .095 washers in it. Should I stick with the .060 that came on the injector or go thinner? Most posts I have read everyone says go thinner. I did come across an older post where Faith recommended .040 with the 190's. Not sure how important the amount of protrusion is with these since they have the correct spray angle. Any suggestions?

Any timing changes made to the pump? I'd say the thinner in the set. Get the spray down in the bowl and leave some room for a timing advance if you plan on it. The washers beneath my 5x.013s are .030" and are the correct spray angle for the non i/c piston bowls. Static timing is only a touch over stock, 1.3mm compared to 1.25mm (12.5degs.).

Timing is still stock, but I had considered the 1/8 inch bump after the install. However, this would probably be dependent on how much smoke Im getting with the new injectors. They arent really that big so I wasnt sure how much benefit a timing advance would get me.
