Is there any way to distinguish between OEM and Crower cams? I was told I have a set of Crower 62403's and I measured the lobe height with a caliper and compared it to the lobe height of a stock B18A cam. There is a .010" difference, but they look exactly the same, if you put the two cams next to each other you couldn't tell the difference. I know that doesn't mean anything because the differences will be subtle, but I just want to know if there is some sort of markings that Crower puts on their cams. And by the way, I can't call Crower because they are closed for the next 10 days I believe.
