Thanks!
I have cranked it with no sparkplugs until oil reached the heads, so at least I know the oilpump is doing its job.
During the priming of the oilpump I also checked for spark, and both front and rear was healthy.
So the next step is to open the fuel taps, pull the choke plungers, give it a good crank and see what happens.
If it runs with no strange noices I´ll let i warm up fully, and then sync the carbs.
Once it has cooled down I´ll check the valve clearences once more and re-tighten the heads.
Should be good to go after that
