Hey everyone, i recently got some billet cams sold as S2 and i believe the guy i got them from as ive seen him sell stuff before and everyine was happy and been around for a while,

Just dont know which one is which as it just has engraved numbers on and none specify intake or exhaust or even that they are S2's,

I have email gsc aswel but thought this might help others if it ever came up again in the future.

I might assume these are the early batch of billets before it was laser etched eith their logo and name on the shaft, but are at least ment to be the revised 274 as i read all billets were the revised cam profile.

Any help would be great,

Quick edit, i see which is the exhaust now as its the only one with a cutout slot on the tail end, but still dont know on version and wanna confirm that

Thanks

intake cam is notched for the sensor, and if for 2g, threaded 8x1.25
I saw that after i posted it but wrote exhaust for some reason LOL.

Just dont know the codes to figure out if they are S2's or not. I dont have my calipers to measure anything on it here

Itd be hard to say without slapping them in a motor and actually using a degree wheel to measure duration.

I had GSC get back to me and they are an early batch, from around aug 2015 they said, co firmed as S2's.

So thats all sorted then, i saw after i posted that only one had a slot for the CAS so that makes it easy to work out.

Thanks for the help.
