O.k., I've been doing some research to get past the lack of aftermarket cams for the NA. I now have a TT cam sensor and pigtail, and I don't understand why no one has tried to mount it in an NA head. Is there a big problem here? I know there's very little meat on the side of the head between lobes 3 and 4, but I'm sure something can be done. Anyone ever tried to do it?
