I have always used the foaming gunk engine degreaser.It works great,spray it on and take a trip to the car wash.Some of those dark spots look like bare block "paint's chipped off".Looks like there is very little grease on that motor.

If you decide to paint the engine compartment,bag the truck.This will prevent overspay on that pretty paint job.

Good luck !!!
