Ported Head
Ported Head
So I'm going to be getting my head ported in a few weeks and was wondering who has already done this, and also what there results were as far as throttle response, iat2s, and overall power
Not on the car yet... bench test show that it's an 11% gain in flow on an average port job and a slight drop in intake temps.
From what I hear, the throttle response improves quite a bit.
The unfortunate thing, is that the head isn't the bottle neck....

I'm also having mine done in about 6 weeks.... I'm having Valves and Valve Springs put in also. I belive I'll have a B 4 and After on the same Dyno. + Post the results...
I was wondering the gains 2, but from what I had heard/learned, its 1 pretty sweet mod. lol pretty $$ but nice
Ported Head + Ported S/C should be a pretty nice setup. Thats what My plan is right now

We ported the head on Gilberts SS, but no real gains to speak of. If you port the supercharger properly it will help more ar atleast the same. You don't even need the head ported unless you plan to run cams anyhow.
So now U guys are saying there wer now real gains? I'd love to see some sheets on the actual flow...
Now I'm kinda on the Fence. $1,900 for this port job could go to buy alot of other things for me.....

What, are they gold plating it for you?
Take it to a machine shop... have them mill out the exits a bit.
Then take it home, mark the new inlet size, and go hard with a sanding drum (only take a bit off).
Then take down any major rough edges.
The point of a port job isn't to increase the size of the ports, but rather to minimize restrictions, and keep the port area relatively the same from manifold to chamber.
And don't mirror polish the thing... you want a slightly rough to the touch finish.
$1900?!?!

+, all that stuff U just said.... lol I got 0 idea how to do any of that!.
I'm Cole Trickle... "They told me to get in the car and drive, and I can drive! But all that other stuff you just said about, tight here and turn there.... I don't know"
If that price is including valves, and springs... it makes it worth it.
The fact that you can run an aggressive cam and rev higher, will actually provide better gains than the actual port job will.

+ what Edubs said, Pulling the Head, + P&P, + Install on the Srping and Valves + install back on the motor.... $1,900 is a good price yes.
But will it be worth it? (I think it should be after the tune and all is said and done but only time will tell i guess)
