Just picked up a brand new, never installed z5 head with valve but no cam for $100.
I'll either port match the head to the intake/exhaust manifolds myself or just have a local machine shop do a light port and polish. (I've tried it myself, not worth my time)
Hmmm...Mazdaspeed made adj cam gears for this motor and web cams does decent regrinds.
I need help. I just can't leave well enough alone.
