Anybody have any close-up pics of a ported JDM 4-1 header? D's site seems to be down right now and I'm in the middle of porting mine. Basically I'm wondering if I'm supposed to leave the flange completely untouched or if it's ok if I open up the hole a little bit. Thanks in advance.

 

yeah sorry... i think that worm kicked some part of our connections ***...

yeah, you can dip into the flange a bit... if you ahve another header gasket, you can use that for a basis....

sorry..

Thanks for the advice, D. I think I'll go pick up a header gasket today to use as a template then. I seem to be using about two sanding drums per runner, so I'm hoping I'm not going overboard with it. Thanks again and good luck with the site.
