with the head fitted, where exactly is it leaking, you say its leaking between 3 and 4, is this the left side, right or cylinder to cylinder?
This is a serious leak that should be blatantly obvious, as its free to leak with zero pressure, so here's my advise.
Check block with a straight edge, compare the block water jackets to the head water jackets, check head gasket with block and head to make sure all holes line up, look carefully at the bolt holes for cracks that might open up under tension, use a sharp instrument in the bolts holes to clean out, then fit all the bolts to the block and measure all the heights from the block to underside of bolt head, then measure that distance through the head.
Was the head crack tested? identify all you water jacket holes and carefully check head/gasket/block all line up.
Is there any coolant flow through the intake manifold, is there any cor plugs in the head that could be leaking.
hope you manage to get it sorted
