Blowing or leaking?
If blowing its likely your tune, and if leaking its bad installation the are a pain to line up just right on the cylinder head

The fel pros are top notch

Multi-Layer Steel
Cometics are MLS, Fel pro also sells a nice MLS

They have no o-ring and dont have to spend the $$ to have the groove machined in your head, they have layers of steel that make up the gasket. They are the gasket of choice, were the o-rings were 4-5 years ago
They come in custom thickness, are reusable and seal like no other. Most hi hp boosted engines run these

You would have to have the orings milled out

getting the heads milled at a machine shop is no big deal, but if you dont wanna do that then yes you have to run lockwires

It would take .010 thou at most to mill the o-ring groove out.

depends on who did the work. i just saw (3 days ago) a set of cast heads that had to be cut .030 to get the grooves out.
