For intake you would probably want around 0.006"-0.007", and 0.007"-0.008" for exhaust.
Have done tappets on a datsun 120y a12 engine which was easy enough with this engine i was a little unsure if I just did the normal Cam lobe or if i had to clear the Vtec as well( turns out i dont) and those measurements in mm = to the same in thous of an " so all is good.

Ty for all the help guys will hopefully pick up the TB kit and water pump tomorrow morning and have the project started by 10am. Will try to take pictures and may even write up a guide if i get all the pics and info recorded.
