What's the deal with GLM? Is it just the crappy gaskets that come with them?

No it is the crappy casting.

Your smart money is with OEM or Barr or Osco.

If you have access to a milling machine, you can "clean" them up but if you have to pay someone to do it, it might be cheaper to just get BARR, OSCO, or OEM......
