Valve sizes?

Does anyone know the stock valve sizes for a '92 4.0L V6? If so, are there any options for using bigger ones? Thanks!

Oh, and if it's not too much trouble, could someone list the wrist pin diameter, rod journal diameter, and piston compression height?

The reason I ask, is that my '92 explorer has 190,000 miles on it, and I know it's not going to last forever. I plan to rebuild it with the comp 49-422-8 cam, .050" overbore so I can use standard 4" diameter pistons, and some heavy port work. I'd like to know what I'm getting into before I start.

Any and all advice will be appreciated. I have experience with Ford FE's, but the fuel injection is new to me. I know I'll need bigger injectors, but how will they work with the stock computer? Again, any advice is appreciated.
