Default Cosworth YB Tecnical,spot key & pointer out !

Hi troops,asking all you boffins on the Yb cam timing.
Easy to time up,yea. But I slipped my std pullys off when timed up,belt attached. And though centre line, notice out .
Head not skimmed severely at std hight.
With a steel rule aliening though centre,notice both key ways out aline ?.
Showing full width of both keys,Not though center of key.
Can see full width of keys "downwards", inlet and exhaust keys.
Got vernier pulleys to fit prior to rolling road, getting the most out by altering cam timing.
TDC set via 360* degree protractor. zeroed off via a DTI gauge,so spot on TDC.
Pistons Wiseco up 0.020 above block face,so when set as above,std TDC pointer shows 2mm past.
Probley I worry to much to get 100% spot on,or just simply re line propyl all on a steel rule.
Be interesting if seen and done out there.
Cheers Pete,on my race engine...
