If I didn't, I would drill and tap the back of the intake manifold and fab a baffle to keep oil out. By simply installing vents you've eliminated the crankase pressure that would lead to oil leaks but you have not provided any fresh air circulation to combat the sludge issue. Ideally you'd want fresh air entering one side or one end of the engine with the exit being opposite. I would also suspect messy oil film/mist around your vents as they are the escape way for all the crankcase gasses.
EDIT- Just noticed that you do have a connection to vacuum, but no PCV? I'd think that would be drawing a lot of air (most probably right from the vented filler cap) giving you a lean condition?
Nice truck man!

Thank you!!! This is the type of info that I was searching for. So I do have a lean issue but it is very slight. The oil looks good so that leads me to beleive that just a slight change in the routing of the vacuum lines may do the trick. Although the truck runs fine it does bog on quick acceleration, but not too bad.
I am going to look closely at all of my alternatives and pursue the best option.
