If you were to remove cyl head with camshafts in place you would have to turn crankshaft one complete turn from auto data instructions. This would make exhaust cam sensor lobe out the way to remove head bolt under lobe. This being the case, both cam wheels writing upside down. I think the cam pegs should be exhaust at 2o clock and inlet at 8 o clock. I have this written down at work and will confirm later.
