my first question, for the gsc s2s, can i run them without doing anything else to the head?
also, i have an act 6 puck but i need a new clutch, what is recommended to hold around 475-550 whp but not having to break the bank with a twin disk?

 

anyone plz?

 

the same clutch you had in there ACT HDG6 lol and yes you can run those cams with nothing done to the head, but do headstuds too its about 80-100 bucks for a set and most shops that do the cams will just through the head studs in real quick.

 

I must disagree here. The GSC S2's are pretty aggressive so springs are HIGHLY recommended by many.

 

If you're looking to go cheap, GSC lists a set of valve springs you can use with the s2's that go for 200.

 

ahh yes very good, i've heard the same or at least within 10k miles of having them in
