AS the title says, why do the oil holes need to be
covered?

if they are not covered and no cam is fitted in the block (as used in a 2TC pushrod setup) then the oil will flow from the holes with little resistance and cause low oil pressure in your engine.

If the 260 head and block were originaly 2tgeu
then I guess the engine came as standard with the dummy
cam.

All the 2T variations use essentially the same block (there are some minor differences though) A 2TG or 2TGEU simply has the oil ports for the cam that would normally be present in a 2TC blocked.

Also, if they have not been covered, what problems can arise from this?

Low oil pressure resulting in dead internals.

I cracked a 2TGEU block once and as a cheap and easy to find replacement I simply found a 2T, stripped it down, had the blocked cleaned, machined, checked etc. The bearings for the dummy cam were removed and refitted 180 degrees rotated so that the oil hole didn't line up, thus blocking the dummy cam oil holes.
