You can create a sid-block.map file instead of modifying rules. See
README.rules:

---8<---
Instead of modifying the Snort rules, you can also create a file named
sid-block.map which has to be in the same directory as Snort's
sid-msg.map
file (typically etc). In this file you can list the fwsam option using
following syntax:

  <sid>:<option>

For example:

   1023: src, 15 min

   Alternatively, you may use a | (pipe) instead of a : (colon).
   This has the same effect as adding "fwsam: src, 15min;" to the Snort
rule
   with SID 1023.

   You can specify options in both places (rules and sid-block.map
file), but
   the sid file takes priority. The file has to be in the same directory
as the
   other Snort config files (ie. sid-msg.map).
