Hoping someone could provide a little clarity on whether or not this is normal? Purchased the car 6 months ago with 9k miles. Driven it hard since but nothing too stupid.
I had my intake manifold off and noticed this buildup on the throttle body , intake manifold and cylinder head intakes. Haven't looked at the valves but I'd imagine they look pretty similar? I was just about to install a blower on this car with 6 months of warranty left.
Appreciate any feedback ...

I recently took my engine down for a cam change and to install forged internals. My engine has 12.5K miles on it. I saw similar oil fouling in the heads and on the valves. I cleaned it all up and put on new valve springs. I put it all together and put an LT4 blower on it. A Mighty Mouse catch can will reduce that significantly if you want to look in to it.
