Stock Fuel System Adequate for my Combo?

I have all stock fuel system, stock computer and the following mods:
- Late Explorer upper and lower
- Stock GT-40p heads
- E303 cam
- 73mm MAF/70mm TB
- stock airbox with k&n
- headers
- 2.5" exhaust

I know I need to get dyno'd to check the a/f, but any thoughts as to where I'm at with fuel? Can the stock pump/injectors/fpr keep up with this combo?
 
You may want an adjustable fuel press reg. and I would upgrade the pump to a bigger pump and it should be fine. 190lph pump would be fine.
