My last 2 builds I fired it up let it idle till I got all the air outta the new injection pump and lines. Then played with the rpms a bit then went for a drive. I think I waited till 500 km before I went WOT. Also changed oil at after the first half hour I ran it. But that was for a diesel not sure if gas is the same

Exactly! When I worked in NASCAR racing, motors were warmed up, checked for leaks, then 1/2, 3/4, and then full pull on the dyno. Full pulls till the torque didn't gain from one run to the next. That's how they new the rings were seated and it was ready to go racing!!

Warm it up first, inspect for leaks, check all fluids and take it for a spin. Basicaly work up to WOT as soon as Safely possible.
As I warm it up I let idle first to make sure nothing is gushing out or arcing then I take it to around 2000 give it a few small whacks of thew throttle to about 4000 then let off and check the temp. repeat the 2000-4000 until I get up to full temp and make sure the T-stat and everything else is working correctly.
As long as there is no major leaks or any thing that looks dangerous I take it on the road and get it on here and there down industrial streets were there are no people or traffic in case something happens. Once I know its good I let it cool all the way down, change the oil and filter, button up any lose ends, bring it up to operating temp, and shake it down some more on the Highway. Once I put 300-500 miles, I give it 1 last oil change before going to regular oil change intervals. But I always inspect it every few hundred miles to be sure everything looks good between oil changes until I put enough miles on to know it's good to go.
Always inspect the Oil Quality and level after to take it out and gradually space it out till you know its good to go between oil changes.
If it gets dirty fast or you notice it has an oil consumption issue Something is wrong and you need to find out why before its to late.

Heat and load seats the rings properly to the walls. This is accomplished relatively quickly and then it's just that downhill degradation to the end of the engines service life.
Get it hot and drive it hard!
