Pulled the valve cover today anyone ever see this stuff?

OK Dude, I went back and looked at the photo of Your set-up, how did You get 3/8" hoses on those carb fittings? Did You "bush" them with smaller tubing?

Thanks Killer6 , that was a lot of info. I took some pix of what it was when I got it , and what it is now. I changed the vacuum to the booster ( Dan's direction last year )pulled it from the intake . I should have checked the vacuum from the larger port , bottom of the carbs ( I never did till now because of the gunk ) the chokes are not connected to anything , but the choke pull offs are. there are only 3 ports on each carb.
#1 and 2 are from today
#3 was how it was when I bought it
#4 holley 1920. larger hole on the right side goes straight to the largest port at bottom of carbs - the one that intake has no hole to match it ? Hope the Pix answer the question you asked me , I got a little lost on some of them.

So I'm thinking no active pcv caused the gunk ? So should I connect pcv hose to the port in the intake where I have the booster attached ( don't know why PO put the booster on - still running original 9 " drums all around , But then again I don't know why they did what they did to this motor? They were also running an electric fuel pump unfused , straight off the ignition , bolted on the top of the shock , even I knew that was BAD.
