eBay header issues

Hey I got a set of eBay headers for my 02 m3 unused and pretty cheep. There was a few spots i had concern that I had my shop welder touch up. My problem is where they mount up to the head is at lot thicker then my stock heads. The only way I'm going to make them stay is by backing the studs out. Has anyone felt with this before, or know where I can buy longer studs? Thanks guys.

just go buy a set of decent headers. by time you get done "adjusting" the ebay headers you will have spent just as much and have a major headache.

Stock E46 M3 head studs are 30mm, when using aftermarket headers with thick flanges you'll want to go to the longer studs found on the E36 (42mm). You'll need 18 of BMW part number 11121744057, I have them avaible HERE. You'll also want to use new copper nuts (BMW part number 11721437202), which I have HERE.

Unless your gaskets are a quarter inch thick, it's not the gaskets. Ebay headers have thicker flanges which require longer studs.

Someone already told you above....ditch the ebay trash, buy a quality set like supersprint, AA, ect.

It's sad to watch some cro-magnon M3 owners butcher the car with this stuff. You get what you pay for. Dude, any time you have to have your "shop welder" touch up a product made in china off ebay is a huge mistake.
