Is there a final word on port dividers!

I did a search on port dividers and found a wide variety of opinions as to whether they are necessary or not. For those who did, (glued, welded or fitted) it was a good thing and for those who didnt they had no negative after effects. There were even some of the guys who did and then decided not to!

A recent post stated the obvious for me..I would like to add headers but I dont want to take apart my head! So am I right is guessing that port dividers are probably more necessary for those who have really built up their engines as opposed to those of us who only run stock? And if I bought a set of FSP headers, I could use the gaskets and no divider and not have major problems? (Waiting until a more convenient time to add the divider!)

So is there a final word on port dividers or are we still divided?
 
why not add it if you are putting on headers...IF you can tack it in there...or if you trust gluing...glue it

if you are in there...why not? its only $15
 
There is no final word, but I am coming down on the side of installing it just because it increases the clamping area for headers. I am having trouble getting my header to seal at that spot and thinking of pulling the head and installing the divider just for that reason.
 
HI
I saw a post a while back where the guy install (welled, attached) the divider to the header and it just prtruded into the head. I think it was a Auzzy race rule applaction (due to no head modifacation) .

The head does not have to be removed to install the divider. It is inserted into the port from the outside in. You likely will have to do some grinding to get it to fit. I suppose it could be welded in, and then have the head and exhaust ports resurfaced to make sure that it is perfectly flat. Doing that would entail hear removal.
 
We can all blame Sladeski. :wink: He is supposed to be dyno-ing before and after with it installed, then removed. There is BEER pending on the outcome (this way, you know it's serious). :shock:

i guess this this is where i get confused :

"The head does not have to be removed to install the divider. It is inserted into the port from the outside in. You likely will have to do some grinding to get it to fit. I suppose it could be welded in, and then have the head and exhaust ports resurfaced to make sure that it is perfectly flat. Doing that would entail hear removal."

so if you weld it you have to remove the head?

from what i understand you have to do some grinding no matter what just to get the divider in right. then you have to tack weld it then you have to cut it flush. the last step would require head removal. can someone clear this up for me? is there a way to do this without having problems without head removal?
 
Yes, you will have to do some slight grinding. I used Resbond 907 GF epoxy to install the port divider. It has been about a year since I installed it and I have experienced no problems at all. I did not have to remove the head. I removed the old manifold and installed the port divider proir to the installation of my FSP header.
 
yeah,

Blame me. I'll get it to the shop eventually, mainly because I need to get my carb jetted up right. Work is just keeping me busy.

i am kidding ofcourse :lol:
 
I think there is a difference, and I think the port divider is going to help, but I doubt it's more then 1-5 HP, not enough to really feel. But...that is a 5% increase, which isn't bad base on the percentages, but when the HP is really the end result, that is not much to lose sleep over if you don't have one and don't want to pull the head off.

I think CHAZ has the definite proof though.

It looks like Chaz was on the gas so hard, that even part of the trunk and rear quarter panels burned up in smoke. :lol:
 
its there...
man, the power out of just a port divider..



(its a weird angle. its actually all there...if I remove the smoke)


maybe I should put a hot babe in the seat next to me....
 
My port divider gave me more top end speed, useful on the highway. It went from 76 MPH top speed to 84 MPH. Didn't really notice any around-town difference, but it must be there if the top end changed... :?

Living at 6000 feet and running full smog controls really strangles these poor things, you know? I recall my college friend in his Comet Caliente (1965 model) with the 200CID running away from my Toyota Celica on the highway back then, and the Toy would run 90 MPH.
