Your example is a bit odd.
And comparing all the columns with one number is a bit odd, too.
The following demonstrates how the header is stored in a buffer header and how control variables inheader and doheader control the collecting of the buffer and its printing, respectively.
The decision if its the header is done by the (NF<12) condition.
Code:
awk '(NF<12) {if (inheader) {header=(header RS $0)} else {header=$0; inheader=doheader=1} next} {inheader=0; for (i=2; i<=NF; i++) if ($i+0>=50) {if (doheader) {print header; doheader=0} print; break}}' infile

Or, as a multi-liner
Code:
awk '
(NF<12) {
  if (inheader) {
    header=(header RS $0)
  } else {
    header=$0
    inheader=doheader=1
  }
  next
}
{
  inheader=0
  for (i=2; i<=NF; i++)
    if ($i+0>=50) {
      if (doheader) {
        print header
        doheader=0
      }
      print
      break
    }
}' infile

elf64_getehdr

elf_getehdr(3E) 														   elf_getehdr(3E)

NAME

       elf_getehdr:  elf32_getehdr(), elf32_newehdr(), elf64_getehdr(), elf64_newehdr() - retrieve class-dependent object file header for elf32 or
       elf64 file

SYNOPSIS

       Command: [flag]... file... [library]...

DESCRIPTION

   32-bit Class File
       For a 32-bit class file, returns a pointer to an ELF header, if one is available for the ELF descriptor elf.  If no header exists  for  the
       descriptor,  allocates  a "clean" one, but it otherwise behaves the same as It does not allocate a new header if one exists already.  If no
       header exists (for one cannot be created (for a system error occurs, the file is not a 32-bit class file, or elf is  null,  both  functions
       return a null pointer.  The header includes the following members.

       automatically sets the bit (see elf_flag(3E)).  A program may use to inspect the identification bytes from a file.

   64-bit Class File
       For  a  64-bit class file, returns a pointer to an ELF header, if one is available for the ELF descriptor elf.  If no header exists for the
       descriptor, allocates a "clean" one, but it otherwise behaves the same as It does not allocate a new header if one exists already.   If	no
       header  exists  (for  one cannot be created (for a system error occurs, the file is not a 64-bit class file, or elf is null, both functions
       return a null pointer.  The header includes the following members.

       automatically sets the bit (see elf_flag(3E)).  A program may use to inspect the identification bytes from a file.
