When I bought my car, it supposedly had EF-1 L28 cams. We just noticed that they have the stock Honda IN/EX markings on them. Usually cams have some kind of marking indicating that they're aftermarket on the flat side by the distributor, but these have none. Are EF-1's like this, or have I been hosed?

 

They could be regrinds, or more then likely, regrinds. Rocket offered both billet blanks and regrinds. As you probably know, the blanks were much more expensive. Paul

 

Thanks man, previous owner also just told me they were regrinds.

I knew they couldn't have been stock, the car idles like an animal!
