1919 motor questions

I have what I thought was a 1914 engine but is in fact a 1919. It was included in a load of stuff I purchased from a 90 year old gent who sold his farm. I was told the engine was rebuilt and set in a Quonset and covered with a tarp without a head on it. It was seized when I got it from moisture. I put MMO, diesel and solvent in a mix and covered the pistons about an inch deep for a week. It now turns freely with the hand crank. Most or the rust on the cylinders washed off with acetone. Hatch marks are still there and pistons look new. I have one sticky valve which I would like to pull and clean. Also the pistons have an arrow on the top facing rearward. Should the arrow not face forward?? Is this going to be a problem?? Also how do I pull the valves? Anything else I should do or check while the engine is on the bench. It looks like the rebuild was done at home rather than a machine shop. I know how to build flatheads but this is my first T. Thanks Bill
 
Rebuilt can mean different things to different people, and sometimes it doesn't mean very much. I'd get the MTFCA Engine book and check everything carefully.
 
Thanks, I have been talking to Jack Innes by email and have decided the 90 year old gentleman who rebuilt this did a backyard rebuild. I ordered the motor and the transmission books this morning and will tear the motor down and reassemble correctly. Pistons are new as are some of the valve seats. Once I know the condition of the parts and tolerances required I hope it will not need a lot to become a good running engine.
Any further suggestions or comments are certainly welcome. Bill

so far the motor needs a cleaning. Valve seats are all new Valves look good but need to check guide clearance yet. (need to clean first) While I am waiting for my books can someone give me the clearances for the rod and main bearings. I need to remove the pistons and turn them around. Is there a correct direction for the rods?? Also piston to bore clearance recommended. Having fun. Thanks Bill
