Not sure if you could call it a problem. It didnt line up perfectly but they put up big numbers anyway with it so I'm not sure how detrimental the effect was.

how much power did you make with those Terminator heads? post a graph please

It most certainly is a problem if Jason from TSP said he's going to be changing the port design.

He didnt have any trouble putting up big numbers with them. If redesigning the port nets even more power then awesome but the fact remains that they work great the way they are. Maybe he's just appeasing the asthetic crowd more than anything, maybe its an actual performance upgrade to the head. I've spoken with them about it and they werent that concerned about it. They didnt think I'd net that much more to warrant sending them in. And you can always epoxy them if your that concerned. Like I said as soon as I can get time with the tuner I'll post my results with the Terms.

I'm sure the Terminators will put up good numbers. They'll be great numbers if the ports are aligned though. Nobody should have to use epoxy a high dollar combination like a FAST 90 and Terminator Heads. Once the problem is fixed, the playing field will be a little bit more even. Here's a pic of the mismatch.

a mismatch is a mismatch...period....if it wasn't a big deal then why port match intakes in the first place??

TSP will fix it and then we will see...that's fine with me

Yea and wont hogging out that runner to match the 90 increase the size if the runner which will then effect the velocity ? What kind of numbers did they put up with it the way it is? Find the that thread and post it or the numbers if you want to be fair. I've seen those pics before. I also have a 90/90 and term setup. Isnt it more and issue with the deck height or something?
What all was really said about it?
Don't you usually port match the intake to the head and not the other way around?
It doesnt look good but doesnt it produce like 480-490? Isnt that what they had on graph?

Damn straight man, that's what I've been saying. You have a fast intake designed to work with all heads, 200-240+ cc intake runners. Do you REALLY think you're not going to have to modify something if you want a seemless connection? seriously....

The main reason most aftermarket setups still run strong and put big #s up with a 90/90 is because the port floor is whats mainly off and it "see's" the least amount of airflow.

And isnt the air being sucked into the intake and not forced so maybe the effect of that lip isnt as dramatic as one might think? Just guessing. I'd like to know if the person who epoxied them made any gains.

Any lip/bump/ridge will disturb airflow and is not good for overall flow/velocity.... so anytime you can eliminate some of that it will help.

Afr's are an excellent head, there is no question about that..... ET just took it a level higher.

I go with others because of $$ You can get a set of Dart Heads, port them out and still get the same performance as a more expensive edelbrock or someone else. Plus Ive used Dart on 3 of my engines with no troubles at all

I gained 43rwhp & 33 rwtq with the AFR 205's milled .030 and stock GM gaskets.

Can anyone put any numbers on the affect of this mismatch?

erikthegoalie

decided to keep my heads for now just cause of $$...I need a 9"-so that comes first..

I can say though that my next investment will be a new motor and some BAD *** heads..

THANKS

I'm not convinced that grinding on that intake runner will offer much of a solution. I'd rather see the intake filled in with a plastic or epoxy. The floors of our ports are dead to begin with. They sure don't need to be any further down.

Ever seen a cross section of a LS4/ L92 / LS7 head? The trend is towards a raised runner.

To add a little to the TFS comments. I just swapped out my old Absolute Speed ported 241 castings for a set of milled TFS heads. I had no problems with clearance with my YT roller rockers and the stock covers. As far as the 215cc runner, I haven't had it tuned yet but these heads are anything but lazy in the low RPM's. The car smokes the rear 295's with ease from a low speed roll and pulls very hard all the way to 6500. I'll have to pay more attention to my friends F13/AFR 205 car and see just how much different they feel in the low rpm range. I don't remember it being much snappier down low, but then I wasn't concentrating on just that aspect. But as a practical matter I'm not sure how much I'm losing with the larger port since the car gets into it's powerband so quickly and I'm never dipping out of it on a shift.
