First, I'd like to start off with a few things before you venture into class tabs to find your class. Currently Epic gems do not get scaled down, so will want to put WotLK, BC and Cata epic gems into any gear on this list over it's rare quality MoP counterpart. MoP gems will give you 8 primary stats and 16 secondary stats.

Second, if you wish to put your MoP legenary meta gem into a t14 helm from sha of fear, it MUST be from heroic mode. The gem can't be placed in a helm under 502 ilvl, heroic mode is the only one above this ilvl

Third, I'd like to mention some other trinkets. The ghost iron dragonling that engineers can craft used with the cogs from Cata will give 42 total secondary stats. You can double up on crit and haste with the changes to hit and expertise gems. This is a pretty good overall trinket. Next is the Touch of the Void trinket, this one is very very strong on single target. If you have one It could be a good idea to swap it in about 30 seconds before you reach a boss. Deathbringer's Will is a solid trinket too, while it could rng give you a bad proc the coolness factor of the procs can make up for it. There is a reason why form procs are going to be a toy in 6.2.2.

If you are an engineer then the MoP engineering helm with 2 cata cog wheels is BIS pretty much no matter what unless you have a very powerful tier bonus. They are scaled to have 42 stats and you can double up on crit or haste with the old hit/expertise gems.
