Turn it with your drill ( check rpm) and watch, that will give you an idea of how the springs are reacting. don't remove the springs unless you need to.
http://www.ebay.com/itm/FORD-MODEL-...r_Truck_Parts_Accessories&hash=item41863762c0...buy & install one of these $35.00 or so SS Model A timing devices sold on E-bay that mounts on one's timing cover & accurately indicates timing degrees immediately above the crankshaft pulley...
I use the B distributor and have/had 4 or 5 out of the 4 or 5 most have had new bushings installed but not drilled for the lube oil to pass through to the bushings.
A couple were frozen up but repairable.
I start at 5 degrees BTDC and tune from there.
