The flat surface idea is the way to go. You can easily see if there are high or low spots that need attention. The head is easy...the top end of the cylinder is a little harder unless you remove it from the crankcase. A good flat surface is essential for proper head gasket sealing but I'd take Joe's advice before doing anything. If it runs good...in spite of what it looks like...leave it alone.
