AU crank will not fit an EF block, the main bearing sizes are different.
The EF crank is fully counter weighted anyway, you can fit the later AU rods to the ef crank though and it would need the use of AU pistons.


Piston to valve clearance is dependent on deck hight and the cam shaft used. there is no single correct answer

It does, which means the main bearing tunnel is bored out bigger than standard EF/EL.
