Deposits inside exhaust manifolds?
Took my manifolds off to redo the exhaust system and saw these little deposits inside the runners. They seem to be oil or coolant but I cant tell. Has anyone seen this or know what it is and the cause? Currently the setup is bone stock Ls1 with single turbo running 7lbs. Get some puffs of smoke now and again and wondering if I'm getting blow by, first thought it was my turbo seals but now not sure. My thought is either rings or headgasket
Any suggestions?

smoke I've been told is more like oil and smells more rich like oil rather than coolant but I agree they do look like coolant. My coolant is currently green though not orange.
