Call the dude and ask him, atleast the HKS ones have markings so you know, with the Tomei ones they dont have shit, so you put them in hoping you have the right ones.
Here's a question for you, on the stock camhafts, near the cam gears, you can put a spanner on it. On the HKS ones you can do the same thing half way down, the stock ones have nothing. Do yours have these?
