Will get WPC'd and a head will be sourced for them to live in.
Ive read this so many times and I just dont see how this happens. Is it the high lift and a strong spring putting too much stress back on the cam?Make sure you have a shop install these. I had two break. On install. BC stopped making the stage three at the time and only had one replacement, and weren't making any more. The shop ended up installing my s1s and gave me the full refund price of 900 in labor. Thats when I went turbo.
