Hi Dirk 73
Without confusing yourself with the numbers, all you need to do is use intake centreline method. Fit cam in motor with the timing gears you are going to be using and fit keys in keyways,use standard 3/8 radius cam followers place a valve in #1 intake guide, obtain tru DTC on #1 piston you can accurately do this with the piston stop method drill a piece of flat plate to fit over head studs and accross cylinder 1 with a nut and bolt in centre of plate that is in centre of piston this forms a physical stop.Rotate engine clockwise till piston touches stop bolt and mark your flywheel then rotate engine anticlockwise to the stop and mark flywheel again and now you have 2 marks on flywheel half the gap between the 2 and you have tru TDC. Then if you have a degree wheel that new mark becomes your Zero, secure a dial indicator above # 1 intake valve rotate engine clockwise till you reach highest lift, then zero indicator at highest lift have a few goes to check it is repeatable,so now you have your intake centreline at highest lift and your crankshaft will have gone past TDC and on its way down take a look at degree wheel in your situation you need it to say 106 degrees past TDC and it will work a treat, however the lower the number the more it is advanced and the higher the number the more it is retarded. it is absolutely critical that you achieve 106. Hope i have helped not easy to explain.
