    Hello everyone! I'm replacing a head gasket on my son's 2012 2.7L Tacoma. I got an OEM gasket set, and the valve stem seals are not marked with P/Ns - one group was in a baggie by themselves, and the others were rolling around with other seals in a bigger bag. My older manual says white spring for intake and black spring for exhaust, but I'm not seeing these colors on these parts. I've seen other posts that describe "brown" as intake and "gray" as exhaust. Please look at these pics - which ones are which? It looks to me like the bronze-colored body has a gray rubber seal, and the silver-colored body has a black rubber seal. Can anyone help and tell me which ones are which? Thanks in advance!
