I know that the valve train clearances where not perfect ( rockers almost touching the valve retainers etc.. and the gaskets where wrong (nothing to do with the failure) - but I never mentioned that the 2nd day of having the car - I tried to start the engine but I was not successful - only after 1hr of trying with fuel pump on - off etc etc.

So here is the story:

After 2-3 times of the ignition button the battery start dying...That was weird...It died super fast.

If you have seen my first video I am describing that it was very difficult to start the engine once - and a big black / wet spot was on my fence that day.

Do you think that the electric fuel pressure caused the carburetor & cylinder(s) to take more fuel and when I tried to start the engine and caused that damage on the valve train?

I am not saying that it is supposed to happen but maybe I left the fuel pump too long? 30sec - 1min? Is that a possible scenario?

Best - Andronikos,
Andronikos,

Your engine failure is unrelated to the fuel system.

High fluid content within a cylinder generally bends rods first.

You had oil pressure failure, possibly high volume pump fitted with a stock Ford oil pump driveshaft.

The shafts do twist as the weak link (factory design), so as to not strip the teeth off the distributor gear/camshaft gear.

As I and others have said, the engine is mix of mismatched parts, the engine builder may need to be involved.

Those rocker arms don't have adequate clearance for the valve retainers. You need a rocker designed for large springs.

Being an Aussie, I've only used Yella Terra or Crane, never had an issue or failure.

The studs aren't long enough for adequate thread engagement with the posi-lock.

You can still fix this, but you'll need some education on the subject, there are many forum members here who can help you.
