Thread: Who would be interested in a 4-1 header?

if you can make a set with a ve specific jig then im in for sure. i dont want t have to ream out the holes on a brand new custom header to fit on a ve, but i may have to if there isnt enough interest in the ve specific one.

im sure it wouldnt be to difficult to make a VE header. he could likely just use a differant flange right and charge accordingly.

Well, educate me on the VE differences. Is the bore spacing and port configuration the same? If it is, then I could use the same jig, if it's in ANY way different though, I'd need a seperate jig for it.

Yeah Matt....looks that way. Just waitin on the flanges for the O2 housings and I'll be started, then looks like I gotta get this stuff goin.

The HS Gen6 headers (one of the links I emailed you last week Damian) worked on both the VE and DE. The ports are different but a universal design can be done so it works fine on both.

you could just order a vvl ex gasket from gregv and then use it with the de one and make a flange that works with both...

from what ive read, you just have to drill the holes out on the flange so they are oblong/ovals and weld washers on to make new holes for the ve. that way the ports on the flange for the de match up to the ve head, so that leads me to believe that the ports are the same, its just the positioning of the header on the actual head

As close as this header will have to be to the upper oil pan to help with ground clearance, I don't think it would be a feasible idea to notch the holes and lift the header 3/16" like you can with the ssac. I know 3/16" isn't alot, but it might be enough to cause problems.

Are you saying that the SSAC needs to be moved up 3/16" of an inch for the ports to match? Seems like a lot! When I used the gasket to eyeball the match, it seemed pretty spot on...

I'll have to look again!

Mine was close to spot on also, the top of the ports on the header was just barely even with the top of the ports on the head maybe over lapping just a touch. I havent notched my header yet just because it would take forever with a drill, I'm going to wait until I can use air.

I just don't think that I would want to make a header that has to be reamed and altered to fit. A big part of designing a header is the initial transition into the runner. You want runners to not impede flow, and you want them to act as an anti-reversion step. From the sounds of it, the two styles require two different headers to be proper and conform to the quality that I'd want to offer.

So, to update at this point, I'm waiting for a unit to jig from the O.P. I'll update when that's received and the jig construction begins.
