I certainly hope they did not use dimensions/ spacing from a gasket that may have been wrong.
Here's a good test to see if a pair of intake gaskets are symmetrical, as they should be in this application. Place them back side to back side and try to line up the ports. Also notice any variances in bolt hole locations.
Ours match up exact with only a very slight variance in hole location. I can't tell you how many heads I measured for bolt hole locations and all were different to some degree so I had to "settle" on a figure. Still, the bolts will go in with plenty of room to spare if the gasket needs to be shifted for any reason. See my post https://board.moparts.org/ubbthreads/ubbt...tml#Post2004008My ports are symmetrical. I wonder if there are really some Trick Flow heads out there which don't have symmetrical port pairs - or if Trick Flow changed the porting. Mine are of the early type with the hole not filled in (ordered mid-October). I'm sorry but how do you know for a fact they are moved an equal amount and symmetrical, you're using a square. Yes, the ports are farther away from the inner bolt holes than the outer holes. It's been that way since the inception of the B/RB wedge. The guys here are speaking in terms of .050" or so.

It certainly appears that azzkikr's pairing of that head and that gasket have good gasket to port/bolt alignment for all 4 ports.
I'd be perfectly happy with that if I were putting it together.
The next question will be, how will the ports of the intake manifold line up when it's sitting on the long block?

Oh, I know the fel pro paper gaskets aren't right.
If I stack two of them, numbers facing "out", line the bolt holes up as good as possible, the port mismatch is worse on one end than the other, but is as bad as about .060".
I agree that "if" the TF port to bolt spacing is in fact based in that gasket, then it isn't correct.
It certainly looks like azzkikr's head lines up nicely with one of those gaskets, so it would appear that at least one head is a match for that screwed up gasket.

I would certainly hope that TF did more than just use a gasket to figure where the ports should go,and would use known factory dimentions for the heads, that being said it would also seem to me that Fel-Pro might want to look at their die's and see if there is a problem there, after all I would wonder how many 100's of 1000's of gaskets they have made and how many time's they have been rebuilt over the years.

I would agree that you'd like to think a head manufacturer would use something other than a gasket to determine a port layout for a new head.
That being said, I've seen many many parts brought to market with things done down right wrong, or existing designs "improved" upon that were just a big step backwards(newer style BB Victor head for example). I've shaken my head in wonder more times than I can remember about what someone was thinking when they designed/produced new performance parts.

I got a ride late yesterday afternoon. I'd ridden in Bill's Dart a few times before and the difference from just swapping heads is crazy! He definitely needs to get some stickier rear tires!  It is, without a doubt, one of the cleanest Darts I've seen.

Sorry if i missed it, but what did the TF heads replace on that Dart? IIRC they were bone stock 452 castings..

Not knowing what cam you got in the dart, even so I bet you got 100hp+ increase over stock 452's, I think TF's flow around 300cfm at .500" depending on the bench etc., My old Cuda 440 went from 11.3 with stock 906's to 10.7 with just bolted on 2.14/1.81 906's that prob didn't flow more than 260 if that!!...gotta be 1 of the best 440>470 head out out there up to around the 700hp mark with pump gas CR in current 240 style, wait till they get the 270 MW version out for 500 inchers+

Sorry if i missed it, but what did the TF heads replace on that Dart? IIRC they were bone stock 452 castings.. Yes - 452's. The Dart is what I'd consider a mild street build - its a toy  - I'm not out to rotate the earth with it. - 8.75 posi w/3.91 gears - 3K Converter - BM Transpack - TTI Headers & Exhaust - X pipe - Comp Hyd Roller (Cam-Lifters-Rockers) In this particular case, the Trick Flow Heads were a really nice jump in power. In contrast I recognize the racers weighing in on this thread are trying to find literally every ounce of power they can get = some mixed opinions. Anyway - I actually printed this thread and have it in the garage in a binder - all the advice/help has been much appreciated
