What Rockers for a stock 94' GT?

[Treview1]

Hey guys,

I have a stock 94' GT....its got some simple bolt-ons, but the engine is bone stock.....

I want to get a nice set of Roller Rockers and new Valve covers.

What would be best for the stock engine, and what valve covers could I get that wont have clearance issues with both the bigger rockers and the intake??

thanks a bunch
