Nikasil Plating AA Biral Cylinders

Hi All,

I was looking at the AA 2.4L 86mm low compression JE pistons and Biral Cylinder kits. Assuming this is a good idea and beneficial, I was thinking of getting the AA Biral cylinders Nikasil plated, but not sure of the procedure. Does the new cylinder bore need to honed to account for the Nikasil plating thickness or is the plating thickness thin enough that it doesn't matter? I researched this forum, but could not find any information.

Originally I wanted to use the original 2.4L Porsche cylinders, but I can only get them safely bored to 85mm.

Thoughts welcome.
