Coyote Engine Prep -Port the heads?

[TheMole]

I am waiting for my complete kit to arrive at the end of August, and in the meantime I have purchased a t56 magnum and a "slightly used" F150 Coyote engine.

My goals are to have an engine of about 500Hp that has a broad power band and is built very strong, so I have selected purchases to eliminate failure points and make it breathe better. Here is what I have ordered for the engine to date:

-Mustang intake cams, valve springs
-Mustang Oil pump housing
-Billet Oil gear and crank gears (MMR)
-Hi volume oil pickup (MMR)
-Ported 2018 Intake Manifold (Auto Mafia)
-Mustang timing cover

What I am contemplating is whether or not to port the heads. It's about $500-$700 (per head) from what I have read. If anyone has done this and could provide info on the value of that, as well as who you would go for that service (Southern Cal is where I live, but I can always ship), that would be great.

I would also like to hear if there are other options at a moderate price tag to increase performance that would maintain the broad power band (all the cams I have seen cost a lot of money for a relatively small increase in HP and all at the upper RPMs).

Thanks!
