What header gaskets to get with TrickFlow heads/Mac Longtubes? Also,header gasket ???

[BlueOvalStangGT]

I searched a little and people recomended FelPro part number FPP-1415 which I found on summit, but I figured since my exhaust ports/primarys are larger then stock, I might need a different gasket. What do you all run? Also, I saw people were using a high temp copper sealer on both sides of the gasket to help prevent leaks, recomended or no?

How much larger are they? The 1415 ports are larger than stock as well.

I dont know, I was just guessing that aftermarket heads and aftermarket headers may be a little larger then stock. Think advance auto parts can get these for me or should I order them from summit?

I bet the 1415's would work just fine.

I used them about three years ago and they still are going a fine job.

I used no sealer or anything like that with the gaskets.

I did use some stainless steel lock washers to keep the bolts in place.

I saw that in one of your posts a while back, and made a trip to HD right after!

That little trick is one of the few things in our hobby that works good and is cheap

Any idea how I can find the part number for these? Or are common stores not able to get these? I rather not spend $10 and wait for shipping if I can get them locally. When I call advance FPP-1415 doesnt come up.

Are these ports(1415) Wider then they are high? This is what it says on Summit:

Port Height (in): 1.250
Port Width (in): 1.480

Mine now are 1.5 in High, and 1.0 wide, and I put the gaskets I have now up against the head, and it looks like
the gasket port can be a little wider then 1.0. So if those dimensions on Summit are flipped, they might be perfect.

I also found these by Percy's:

Summit Part Number HP-68014 Which are 1.650x1.250. Is that too big? Here is the description listed :

Why not go to FelPro's site

I went to Summit & Jegs to take a look.

Both show a size of 1.25 & 1.48

Summit shows 1.25 H & 1.48 W
however
If you look at the pic, the largest distance is H, NOT W.

Looks to me like the correct port size is 1.25 W & 1.48 H

No one has tried the XX Carbon ones by Percys?

 

[BlueOvalStangGT]

I bought the Fel-Pros, but bump so see if anyone has anything good to say about the Percys...they sound neat.

 

[94gts]

are your headers 1 3/4 or 1 5/8?

I needed FelPro 1487s for my AFR 205s.
