Just got my head and block surfaced, and I want to put on a cosworth metal HG, it seems all of the metal HG's are 87mm and up. I'm using stock 86mm bored, would this be a problem running a 87mm HG?

This. It's fine if i can make one suggestion though. Spray the gasket with the copper spray before you install it. I have reused my Apexi and it still holds perfect leakdown. The Copper spray really works well to seat the gasket.
