That's wired because that means you have a 85mm piston.on a H22.Was your block reslevved??? Call up Ross direct and find out, as far as I know the B-series pistons will work in a H22 as long as its reslevved for it.

 

my block has darton sleeves

 

Compare it to a stock piston or put it in the bore. If you have a 85mm piston with a 87mm bore you'll know it.

 

9 out of 10 times that is just a reference number for the piston manufacturer. They use that 85 mm forging for a number of different sizes, 85 mm probably6 being the smallest! Look at the part number for the piston, and not the forging number!
