Ops sorry ...

public function BuildHeaderBlock( HeaderID:uint, DataTypeID:uint ):ByteArray
{
 
 //
 var BlockHeader:ByteArray = new ByteArray();
 BlockHeader.endian = Endian.LITTLE_ENDIAN;
 
 _blockId++;
 
 // MATERIAL BLOCK HEADER
 BlockHeader.writeUnsignedInt( HeaderID );   // Block ID      32 +
 BlockHeader.writeByte( 0 );       // Block namespace handle  8 +
 BlockHeader.writeByte( DataTypeID );    // Block data type ID   8 +
 BlockHeader.writeByte( 0 );       // Flags      8
 BlockHeader.writeUnsignedInt( 0 );     // Block data size in bytes  Offset = 56 bytes
 
 //
 return BlockHeader;
 
} 

Bits not Bytes, 1 Byte = 8 bit, so the offset, in bytes are:
uint32 ( word ) = 4 bytes +
byte = 1 byte +
byte = 1 byte +
byte = 1 byte =
7 bytes. The first byte are at index ( offset ) 0 so the 8th byte are at offset 7
