I blew out the spark plug and heli coil on my 2002 town car and was told by the mechanic that my only option was to replace the heads. Do I have any other options that won't cost $2000?

Yes there are! This is a not-uncommon issue with the modular motors. What you need is a spark plug thread repair kit. Here's a link to the one approved by ford in a past service bulletin:

Thread Repair Kits

Bear in mind, however, that it is possible that your head cracked when the plug blew out. Unlikely, but possible. In that case, you would have to replace the head unfortunately

Thanks, which kit would I need since I've already blew out a heli coil repair kit?

I used calvan 38900 on my truck with 5.4. I believe the inserts are oversize to account for a previous failed heli coil repair.

Here is a link to a Youtube video I did with the kit when I repaired my truck if you want to check it out.
