hi guys, im in need of some help with the valve clearences when fitting a newmans ph3 cam. i know standard is inet-0.20mm and exhaust-0.40mm but on the data sheet from the newmans website it shows the below
inlet-0.008mm exhaust-0.010mm
0.203mm 0.254mm

im just confused by 2 sizes shown for each and was wondering which size to use.

0.2 inlet and 0.25 exhaust is what my piper 285 uses in a vtr. So id expect it would be more or less the same with the ph3 as its more or less the same cam.

Hope that helps mate :)
