If you have some money lying around.....http://www.ebay.com/itm/RAJO-Overhead-Valve-Model-T-Ford-1914-Rebuilt-Engine-Tra nsmission-Rare-NOS-SCTA-/371512006626?hash=item567fd757e2:g:8eYAAOSwo3pWdPa4&vxp =mtr
The money is a bit of a stretch for a guy that knows Rajo heads. The model 30 is bottom of the barrel, performance wise, for the 8 valve heads. Some call it the commercial head for trucks. Still looks cool on a speedster. The engine may be worth good money, depending on what was done to it and by whom. I suspect the head and engine will wind up separated.
