There are so many variables. MHS, Livernois, Fox Lake, and TrickFlo make excellent aftermarket heads. For people who don't have access to an EXCELLENT machinist who has been porting heads for 50 years+, those companies are a good idea. I had my PI heads ported and polished by a local legend who has been doing it for almost 50 years. He charged me a fraction of what the other guys cost and the flow numbers far surpass them.
You can P&P the stock heads but you really need someone who knows what they're doing. Otherwise, go with the aftermarket guys.
Port and polish, valve job, titanium valves, GT40 rocker arms and some heavy duty valve springs.
That is the master plan my friend! GT40 Rocker Arms a good fit on the PI Heads?

You know I was wanting to do something to the Stang in the performance area, would port and polishing heads on a lightly modded 2v be worth it? How much did you spend like $300 or $500? I mean I only have an o/r midpipe and my SCT tuner for performance but nothing major done to the motor...
I have been quoted $1750 for p&p and installation of any parts I supply for the heads. The speed shop has guaranteed 55+RWHP with adding valves, springs and a mild cam i already got sitting in the garage.Or the Dyno run after install is free. I'm taking it in Monday morning!You would gain a little, don't hope for huge numbers. On a car like yours, Id say maybe15-25rwhp depending on the work. Mine costs me quite a bit ($1500) because I had a LOT done, basically rebuilt the entire head with top quality stuff.
