I received ported and coated ex mani and o2 housing from one of vendor here. Both got coated inside and out. It was kinda poorly wrapped and saw some dents on ex mani surface. Perhaps shipping damages from o2 housing that was in same box. But I don't know how this happened. Is this good to go? BTW, One member told me they should not coated on sealing surface. Is this true? Tell me what you think. Thanx a lot.

Couple of nice nicks there, should be fine though. If you so desire you can take a buffer wheel and clean off the sealing surface.
