If you have left the engine at tdc, install the cam with the scribe marks in line with the mating surface of the head, fit sprocket and chain, and push chain tensioner in by hand to make sure all timing marks line up, obviously fit sprocket bolt, then turn engine to fit second bolt..

once happy timing lines all aline tighten bolts and knock tabs over, fit tensioner. set tappets 4 in 8 out

at this stage turn engine over by hand, to make sure timing is correct and valves dont hit the piston.
If it aint sharp I can play with it

if it aint, then make sure it is, or you will be removing the head again to change a pair of valves, and maybe a piston.

small inspection plug top of left casing, facing forward. you will see the timing marks.
