Plenum Pull: gunk in runners?

[ammrpm]

I was able to get the plenum pulled successfully with everyones input. Thanks!

Now that I have the plenum pulled... I am able to see a lot of gunk in the runners of the plenum and I/H. Is this normal? Here are some pictures:

Cylinders 6 & 8 seem to have a lot of oil being passed in the runners:


Closup of cylinder 8:


Shots of other cylinders:



Should I be worried about any of this? Should I try to clean any of this out?

Thanks!
