The engine will be top-heavy. Be very careful when you try to turn it with the cylinder head to the down position. Use something thick and heavy like 3/4" pipe couplings as spacers between the stand plate and the back of the block. Does the front of the stand extend past the front of the crankshaft? Stovebolt engines have a nasty habit of tipping engine stands over, and crushing/amputating toes in the process!
