I think the only way to "fix it forever" is to make sure the deck surface is totally flat, make sure the heads are totally flat and not cracked, install head studs, and get headers with a different crossover that doesn't concentrate so much heat on the back of the heads.
MLS is the only option worth spending the money on, unless you like saving a few bucks to do a job again later. I'm sure ted believes what he sells is great, but any business is going to tell you they back what they sell. Would they make any money if they didn't? This has been hashed over and over and over, add nausium. People will always overlook the 9 people telling them to avoid product X and go with the 1 person telling them the option they proposed is fine, just to re-affirm their desires.
Spend the extra money and do it right or complain later on a forum about felpro gaskets
