Lift with 1.6 ratio rockers .445/.444
Intake opens: 20* BTDC
Intake closes: 76* ABDC
Exhaust opens: 67* BBDC
Exhaust closes:-19
Lobe separation angle: 115.5
So with this info John, you can degree your cam from the .006 figures.
The .050 figures look backwards, I think it should read 276/266 @ .006 AND 210/206 @ .050.

If the intake does only have 206 @ .050, then your timing would be open at 11.5 ATDC, close at 37.5 ABDC. Intake centreline at 115.5 ATDC.
Of course this is "tongue in cheek" since we don't know the timing of the ramps.
