Hello guys, I got this cams a while ago from a member here and seems he is no longer active on the forums.. anyways the seller claims they are GSC S1 for my evo 9, but I want to be 100% sure before I go ahead and install them.
Please look at the pictures and tell me if they are in fact S1 cams, they only have the S1 engraved on the end of the cams, you can see that in the pictures, there is no other numbers or markings of any kind on them.
Also, would you recommend I use them even though the intake cam has a couple of nicks on the lobes? can I smooth them? if so, how?
Thanks a lot guys,
Ed

PS: I have already sent Greg from GSC a PM, he hasn't answered yet so I figured I could ask here also

 

The first "nick" picture you can see another "nick" on the next lobe as well. Those nicks are in the path of the rocker arm as well. I assume you can feel them with your finger nail. I would assume gsc would recommend buying new or using undamaged cams.

 

Yes I can feel the nicks with my finger, and there's 3 more nicks but the one pictured is the biggest of them all. So, I can't get away with smoothing the surface down? most importantly, are they even GSC S1 cams?

 

A machine shop could smooth the ridge... But i dont recommend then either way

 

Smooth the nick so you can't catch it with your nail and run it.

 

that looks pretty deep from the picture i wouldnt use them but thats just me

 

^^^ This. If you can't hook a nail in it and there is no ridge or bump then the rocker isnt even going to know its there. They are definitley after market cams, nice big round lobes-- can't verify manufacturer, since the seem to be GSC, send them a note and pick and see what they say. They are a vender here.

 

Solid advice, thanks a lot, I will go ahead and get that fixed, I would however like to know if this are in fact GSC cams.... I sent GSC a PM, let's see what they say...
