I find it hard to believe that such a small amount of extra clearance would make a noticeable power difference. It will make a difference, but think about the physics involved here. The valve opening and closing times and lift are hardly affected by such a small amount of extra clearance.

I'd expect a little more noise maybe, bit I would be looking elsewhere if power loss is noticeable.
