Engine back from machining! What next!

I've only assembled one engine and I did just what everyone here has said.Use paper towels not cloth rags to clean(read this in my assembly book) watch for sharp edges.Bottom tap all the threaded holes.Take your time,have fun.Knowing that you assembled it,It's a real blast when you crank that beast over for the first time and she fires off.Makes me want to do it again.....hhhmmm
