Hi "sharp", try to find a shop who will use a block-plate to finish-hone the bores, it's fairly important on these Flathead castings!

Also, make certain you have it pressure-tested, do not rely on "magging" only!

Thanks, Gary in N.Y.

P.S. Would also strongly recommend some stainless valves and some bronze-lined guides so there will be no valves "hanging" down the road.
