I loved this video! This is the exact same stuff we're learning in school. Down to the VGS-20 The video is quick and doesn't show all the steps in detail but you get the idea of what he's doing. First he reamed the guide and then honed it to its final size. Then he checked it with a guide bore gauge. After that he cut his seat angles (two angle seats it looked like?) and lapped his ALREADY GROUND valves to check the valve job's accuracy. Pretty basic stuff if you ask me. :D
at my shop we made the hand lapper fit into a drill, then we put a compression spring under the valve in the head to push up on the valve, it works really well,very smooth.
I read about the Arbarth 1600 OT powering to 7500 with redline of 9000. I bet that was a 2 cam like the Lotus 1600. I like the combustion chamber shape; reminds me of a flat 6 porsche aircooled cylinder head.
I would like to know how much larger the valves were and whether he sunk them or not. Also what angles he used.

great show sir,
I,m really interested with this kind of work. That makes me have a lot of question. If you don't mind answerring
1. Why drilling the valve guide ? do drilling are requires for every new valve installation.
2. Why dont you cut the valve, instead lapping them only. If its titanium valve are you going to lapp them ?
3. Is that a micro meter you are using ?
thanks, i hope its not bothering you to much.
