I ordered a set of cams from Summit racing, they sent me two different cams, so I'm sending them back and getting my money back. What cams should I buy? I have all the bolt on parts necessary, and AFM cam tool. Is there any way to change the valve springs on these cars without taking the head off? Is there a tool you can buy? If there is where can I buy it? Thanks GUYS for all your help, I have my car ripped apart thanks to those bastards at Summit. Need help quick........Thanks Danny (Shadow Grey 03' GT)
