RB 413 IS IT WORTH TO BUILD
This is easy to tell, "high mount" water pump, and usually instead of the center heat riser passage being hooked to exhaust, it goes to coolant, and they seem to use "Ford" huge 18mm thread plugs. Some have 6 bolt, others have 8 bolt cranks. Other than the water pump/ heads/ intake the block and crank are OK. There are both 413's and 426's made this way, I don't know about 440. One nomiker is "426-3"
High mount water pump
See the water temp probe in the middle of the exhaust? That is COOLANT there, and those ports are different. The intake heat crossover is also coolant
