Wrench Split: File into multiple and keeping the same 3 lines from input into all output files

The following code will split the infile into multiple files. However, I need it to insert the same first 3 lines from the original input file into each splitted file. How do I modify my script below to do so:

Code:
print -n "Enter file name to split? " ; read infile
if [ -z "$infile" ]
then
echo "Invalid file name entered ..."
exit 255
fi
print -n "Enter Number of files to split it into? " ; read numf
if echo $numf | egrep -q '^[2-9]{1}$'; then
echo
else
echo "Invalid number <$numf> entered. Entry must be numeric and 1 digits in length and between 2 and 9 ..."
exit 255
fi
echo "Splitting file $infile into $numf files ....."
sleep 2
awk '{a[NR]=$0}END{for(i=1;i<=NR;i++)print a[i] > "'split.$infile.'" 1+int(n*((i-1)/NR))}' n=$numf $infile
echo "Done...."

MAKE_SOCKDFR(8) 					      System Manager's Manual						   MAKE_SOCKDFR(8)

NAME
make_sockdfr - Generates frozen route file for SOCKS server SYNOPSIS
make_sockdfr [infile [outfile] ] DESCRIPTION
make_sockdfr reads in a plain-text route file for the SOCKS server and produces a frozen route file as the output. Both arguments are optional. The default for infile is /etc/sockd.route; the default for outfile is /etc/sockd.fr. You may specify infile while omitting outfile, but you cannot specify outfile without also speficying infile. The contents of the frozen route file is essentially the memory image of the parsed input file. Using the frozen route file can reduce the start-up delay of the SOCKS server program since it no longer has to parse the file contents. When the SOCKS server starts, it always looks for the frozen route file /etc/sockd.fr first. If that file is not found, it then tries to use the plain-text route file /etc/sockd.route. If you use frozen route file, you must remember to run make_sockdfr every time after you modify the plain-text file or the SOCKS server will continue to use the frozen version of a previous route file. To find out the contents of a frozen route file, use dump_sockdfr. FILES
