you know what i hate to say this but now with all thats been going on im starting to question everything. today is my day off im gonna pull off my VC to make sure i have the correct cams in my car. i gave them a set of bc 272s and well now im just questioning everything. im pretty sure there should be some engraving on them can anyone verify that for me? and where to look and is there any way to tell if i have aftermarket valve springs by sight, cuz that should be in there as well.
