Maybe you can help me with this question. What valve springs do you run with the P11 head for turbo? 115? or 138? I remember a few years ago Mazworxs warned about using the 138's because they were showing abnormal wear on the cams? I just don't want to spit a shim out if I bounce off the limiter @9k with N1 cams.
