The valve sizes in the Ford FE engine can vary depending on the specific model and modifications made to the engine. However, here are some references from the search results:
– According to a forum post on the 332-428 Ford FE Engine Forum, the valve sizes for the Ford FE engine can range from 2.020/1.55 to 2.090/1.65.
– Another forum post on the same forum mentions that 2.19/1.75 valves can fit in a 4.05 bore with some modifications.
– The Ford FE engine specifications, as mentioned in the book “Ford Performance” by Pat Ganahl, state that the standard valve sizes for the FE heads are 2.02/1.55 inches.
– A forum post on the Ford Truck Enthusiasts Forums mentions that the stock intake/exhaust valve sizes for a 390 engine are not specified.
– The book “Cylinder Heads and Valvetrain Interchange for Big-Block Fords” states that the valve sizes for standard FE heads remained the same at 2.02/1.55 inches.
– The Edelbrock #9704 valve guide is mentioned as a Manganese-Bronze Valve guide for all Edelbrock Ford FE Cylinder Heads.
Please note that these references provide some information about the valve sizes in the Ford FE engine, but it is always recommended to consult official documentation or consult with an expert for accurate and specific information about a particular engine.

390s had 2.04 and 1.57 valves. I think you can use 428 heads on a 390 without running in to a problem. You will then have 2.09 and 1.65, which is the same as the 427 LR.
What is the right valve size?
Valve Sizing
A general practice to determine the correct valve size is to use the equation Q = Cv√(ΔP/G), where Q is the capacity in gallons per minute, Cv is the valve flow coefficient, ΔP is the pressure differential in pound per square inch, and G is the specific gravity of the fluid.
What size are the valves on a Ford engine?
Standard valve sizes are 1.94-inch intake, 1.60-inch exhaust, but these can be increased to 2.08/1.65 on the aluminum head and 2.125/1.65 on the iron head.
