Dart CNC 227 and felpro 1205 gasket?

I was wondering if you can get a good enough seal to use the 1205 felpro gasket with the Dart 227 CNC heads? The intake I have will only fit up to a 1205 and doesnt have enough material to fit a 1206. If anyone wants to know it will be on a 406 with a SR cam.

Thanks
Jeremy
