Square or Oval

[Mr. Stroker]

OK, what would a 351W out of a 95 bronco have for its exhaust ports. Square or Round / Oval??

Oh yeah, and the flowtech longtubes that I bought for the 351w had ovular ports on the tubes too.

 

[Mr. Stroker]

lol.... Well looks like i got a couple things goin back to summit lol

 

[Mr. Stroker]

Its all good in da hood, my fault for not checking for sure before i ordered them. No biggy im just phyced about those headers they look killer for stock.

 

[Skandocious]

I really don't think they're square ports... Junior ported his heads.


JUNIOR!! Where are those pics of your heads that posted!?!? EDIT: Nevermind, those are GT40 heads.

 

[TheRoadVirus]

GT40 heads have the same ports, if I'm not mistaken. It's only the GT40P's that don't.

 

[Skandocious]

Interesting... If they've got square ports then why do all the headers that guys use on these trucks have ovular ports?

 

[Mr. Stroker]

My lightning headers have square ports.

They're not square in the real sense of the word, as in ninety degree angles. They do have some rounding (for lack of a better word off the top of my head) to them.

Here's the only decent picture I could find of the exhaust ports on GT40s.

See? Square.

 

[Storm]

Most 351W i've seen are like that.. Square but rounded at the corners..

 

[flareside_thunder]

Yup, square with rounded edges......my headers have round pipes that are I guess crimped into a square port to match up......I think the square ports allow for smaller tubes...iono it's late and I am dog tired just throwin bones.....

The header gaskets are more roundy then the heads. I always get the Mr. Gasket ultra seals. I think they had the roundy ports. They work so good. Ill have to take a pic next time im out. Just dont use the gaskets that came with the headers. There junk. And stock for stuff has the propper looking ports to match.

 

[Mr. Stroker]

yea same with my lightning headers, round tubes, square ports.

Found Juniors gt40 head pics in his gallery:

Here is my 393Windsor. E7TE heads. You can kinda see that they're square.
