no.. my fuel head is modified by flowtech. it's the old imagine auto modified usa fuel head so it is already shimmed to higher pressure.
i think you'll have to experiment with them.

the shims in mine are probably around .010" - .020" thick each and there are 3 stacked together but i never measured the thickness of them.

you can email Larry at CISFLOWTECH
