66\' 6cyl w/headers... Is the port piece important?

Hi,
Is the port piece available for 200ci's that sits welded to the heads behind the headers to divide the center ports important? Or is it just to add hp? Thanks!

What the heck are you talking about? Port Piece? Am I going to have to buy something other than hedders for the Falcon?

66\' 6cyl w/headers... Is the port piece important?

The port divider is available from Clifford Performance for about 13 bucks. It needs to be welded in place. Some have tried to use high temp adhesive but it comes loose and creates a bad rattling noise. It is not necessary and you will not feel a seat-of-your-pants performance increase. However you wont feel much from just a header by itself either. The head is the problem. Later heads 69 up had more intake tract volume and bigger valves. You can get 1.75 intake and 1.5 exhaust vavles and together with a three angle valve job with a 30 degree back cut on the intakes you can make a difference. Do some porting and polish install a high lift cam, 1.6 ratio rocker, dual roller timing chain from classicinlines.com and you will feel the difference. Finish off with a Duraspark from a 78 or later 200 with msd 6 ignition or duraspark module along with a direct mount Holley 350 and your header and your power will be close to a stock 289/302 without as much weight on the front.

Or you can wait until classicinlines releases it's aluminum head for the 200 later this year. The future is about "Keeping the Six"

GT, can you please re-explain to me this Port Divider and why it is helpfull or unhelpful?

Mostly though, what the heck is it...?

I'm building a 70 200, +.040 with 1.499 exhaust valves, porting all to berjeezus and back, and probably a tri power setup. I'm shooting for 200 HP with 200 cubes, adn I am staying ALL Americal Parts, no Aussie stuff.

It's a little piece of iron that goes into the siamesed ports in the head. I'll show you a picture.

That port divider is basically to separate the Siamese ports 3 & 4. It gives the 200ci a bad a$$ sound dude! I swear it sounds CLOSE to a 289! Yeah I know it's not a v8, but for a 6, it sounds pretty dang close! I'll post a link to a YouTube video so you can hear the difference with that port divider in. An H pipe with Flowmaster 40s and 2.5" piping gives it the best sound. The X pipe ain't really necessary considering a 6 doesn't make a lot of HP. The H Pipe is perfect.

I can now attest to the sound performance betterization.

This car sounds GREAT with dual exhaust and split headers! It's like a 70's Buick 235 V-6 with a super charger on it
