Cometics take too much work to get a proper seal. Cosworth have proven to be great headgaskets at they're not too expensive.
Tomei's, Ichiba' and megan manifolds all crack eventually. The extrude hone porting and swain coating method will probably run a little more than a tomei manifold, but is definitely worth the extra expense. I suppose you could save a little by opting for ceramic coating...maybe?
