I'm thinking about Port and Polishing my heads because of the poor air flow. I just wondered (and have done a search) if this is a worthwhile mod? I know it would be more effective to replace the stock heads with maybe Patriots, but I wondered how effective the P&P was. Thanks for the help.

as far as i know the Patriot heads are stock heads ported. Someone please correct me if im wrong.

There aren't any true aftermarket heads for the 2v 4.6 that comes in these cars. Companies such as Patriot Performance, Fox Lake, DSS, or whatever just use stock castings that have been ported and depending on the stage come fitted with bigger valves.

Its definitely a worthwhile mod for these engines since the heads and cams are the major flow restriction. That being said, a set of ported heads isn't gonna net you much power at all over stock without a good set of cams to go with them.

I will def put that off till I get my bolt ons done then start with valve springs, cam, p&p heads and valves.

yeah its a worth while mod in the long run but if your not planning on building the engine up then some built ons are always a good way to start depending on your goals. glad to see you traded the cobalt in for a real car

haha yea the cobalt was my get to school and work car. It was a nice car for gas but when i drove the mustang I had to get rid of the sloblat!

port and polish, no not really worth it, cnc and angle job w/ the port match and polish - yes worth it, - oversize valves, better springs, cams and all that

LOL What? You do know that every CNC made head out there started with a hand ported head to set the program.

9 times out of 10 hand ported heads will out flow cnc heads.

unless your putting bigger intake and exhaust valves your wasting your time, if your gonna tell me a polish job will out flow a re-size and polish... I got some beach front property in Arizona I want to sell you
