Hi I've had my predator 212 for some time and always knew the previous owner did some mods to it like billet rod and I believe bigger valve spring but recently I've been wondering about my cam, I am not sure if my cam is original or not as some of the oem cams have waffled textured rivets head while some don't I will post some old and bad photos of the cam the last time I opened my engine if anybody knows please let my know what kind of cam I have thanks.
