PERL editing single line in file with regex

Hi all,

I am having some trouble in altering this bit of codeL
while (<FILE1>) {
($hash, $input, $for, $aa) = split( /\s+/, $_) if /^\# \input\b.*/;   

if  ($aa =~ /LEU\b/)  {s/    (.*)/$z3leu  $z2leu  $z1leu   $1/}  
print;                 }
Need to alter so that it only writes to the first line of values and not the second, which is the case here, FILE:

# input for LEU
0.987 0.654 - write before these values what is stated in s//;
0.587 0.211
