hello all i have a 92 civic cx with a z6/b7 mini me in it and i was just wondering if anyone knows if there is a way to tell if the cylinder head has an after market cam in it with out tearing the cam all the way out? i bought the head from someone that did a lot of work to it but i just wanna know if its the stock cam or aftermarket?

all help is appreciated thanks

 

Remove the distributor, and look for markings on the end of the cam. Rotate the motor by hand, and look for markings on the sections between the lobes. Near the cam side, look for a small hole traveling through the cam.
