Default More power for an 04 Grand Marquis

I have an 04 GM and have added dual exhaust, K&N air filter, 5.4 litre throttle body, Trick Flow upper plenum, MSD coils, 24# injectors and underdrive pulleys. It is not much faster than it was stock. CNC heads are $1500, a programmer is(GOOD ONE) $500.00, which one will give me the biggest increase in power?

It's the same today as it always was -- speed costs MONEY !!
The question is: How fast can you afford to go !??
Ya gotta face facts, man -- that 2-ton car ain't gonna impress anybody, no matter how much time and/or money you spend.
The Grand Marquis is an old-man's car. I know this because I'm an old man.
I have spent many dollars and many weeks, days, and hours in the process of restoring/modifying the 95 MERC.
I set it up for long-distance, high-speed touring over the deserts and mountains of the American Southwest, with many trips to Mexico and Canada, as well.
In YOUR circumstance, I would suggest that you stop spending any more money on "parts" -- get the car "tuned" by a professional tuner, and LEAVE IT ALONE !!

Bye-Bye !!

What sort of tune, dyno tune? Wouldn't that be a programmer in conjunction with a dyno? I'm pretty sure no dealer is going to be of much help.
