The standard bore for an H22 is 3.425 or 87mm, i purchased wiseco pistons (STD Bore), i am getting the block sleeved with Darton flanged sleeves, Darton states on their web-site specifications sheet that their bore in the sleeves is 3.415, thats 10 thousands interference?????? does that mean that the sleeves must be bored after installation or is this a typo on dartons website? Any help is appreciated

 

The sleeves are installed to a rough bore size and then they must be bored/honed to your finish bore.
