Nope, the cams were timed perfectly in relation to each other.
However:
When the engine span backward it compressed the hydraulic tensioner that keeps the cam-belt taught.
Upon starting the engine the crank span without engaging the cam-belt enough to spin it in time, so effectively the timing was advanced approximately 25% when the tensioner brought the belt back up to operating tension.
Hence 17 of my valves hit the pistons.
Second hand turbo head from a scrapper, valves out, back-cut, lapped into the existing head, re-timed and fired up.
I am a happy man.
