Wh1e oil return flange

[Raymos24]

So I have one final question before I finish building my -12an return line setup for my Wh1e. So most holset users are using the flange from Racepartsolutions.com that is labeled as their "T6" flange which is for a 3/4" npt. However the opening on that flange is round. Most holsets have round openings for the oil return however, H1e's have a square opening (pic provided". Will I be ok running this flange, with a gasket that has a square opening, or will I have to turb somewhere else?

The flanges bolt pattern is the same between the H1 and HX turbos- the H1 turbos have an outlet hole that is closer to a Garrett design.

You MAY have difficulty getting a -12AN line to fit between with the backplate and v-band compressor cover design of the H1. Don't be afraid to grind a little once you get the cover clocked where you want it.

I actually got it to fit already. I know the bolt pattern is the same but I mean the opening where the oil comes out of. In the pictre the opening is square (like on my turbo) but on hx40's the opening is round. The flange also has a round opening. Will my square opeining not work with a flange with a round opeining?
