i looked into vengance porting today, its actually cheaper to buy his intake ported and the throttle body separatly then getting texas-speeds 1,069 dollar package deal and sending it out to be ported.

I think the reason that Ron @ Vengence stopped accepting customer supplied intakes is because of the liability in porting a used intake. I'm guessing that he may have gotten an intake or two that an attempt was already made to port it or he got an intake that was broken. What if when he gets your intake he finds that it has a crack in it due to prior installation, what does he do then? If he's porting a new one, he would return it to FAST and grab another intake to port for you.
I can't blame them for going about it this way. They want to start from scratch with a box stock, fresh intake. I'd have to guess that head porters are the same way. How many will accept your heads for them to port.

Not sure what that means there tough guy, but you might want to reel it in a bit when you don't know who you're talking to. I gave him my opinion, you gave him yours. Now go post in some other thread how you made 400+ with a HOTCAM and straightline's butts smell like roses.
To the OP: It might be a little more money, but someone like Tony Mamo has been porting tons of these, with results, and has had them actually flowed to provide hard data of what his porting does. I would send it to AFR.

Now if its a FAST on a stock set of heads, (not really cost efficient in the first place) then yes, it may only be a few extra horses. but those numbers are low for an aftermarket set

I am going to port mine myself. Try a search. there is a thread around here somewhere that explains pretty well how to do it and includes quite a few pics. If you are afraid to mess up a $700 intake then I would get a ported one from either Ron at Vengence or Tony Mamo at AFR. Just my $.02

The amount of gain is dependant on a couple of things. 1: Does everything before the intake flow well enough to keep up. Specifically the maf, intake lid, filter. 2: Do your heads flow enough to warrant the additional flow demand from the intake manifold. 3: Is your cam aggressive enough to justify the needed flow.
Case in point: If your heads flow 300 cfm at 600 lift, but your cam only has a max lift of .550, and the heads only flow 270 at 550, then you may not need the intake ported, or you may only see a slight gain from having it ported. But down the road, if you decide to swap the cam to a slightly larger lift, your intake manifold won't be the restriction in the flow path.
