It is a Alphawerks header
Please take a look

Is the gap too big?

Is it normal?

looks like you may have a little bit of a leak when tightened, however, this is just a guess.. Once the bolts are tightened it will close the gap down on the gasket more.
Looks like a toss up... IF your going to be doing the install yourself (not hard), I say get em on there, tighten them up, and see if you hear any leaks.

If there is an issue with a leak you can contact Alpha Werks for warranty work. PM me if you want their number but your best bet is to try and tighten them first and see what you have or you can contact them before that. 1-800-758-9105

Same shit happened to me, mine were much worse though. I had a gap of about 3/4 cm. started the warranty process over a month ago and supposedly they're coming this week. Much grief and unnecessary shipping and brokerage fee expenses because I'm in Canada (I think you're ok if in US). Also they don't replace them but rather fix them so I have no clue what to expect from that either. And also check if the flange where the 3 holes are is flat too (just put it against a flat surface and see if it lies flat or kinda rolls a little), mine weren't. 2 thumbs down for Alphawerks quality control

That sucks. You may be able to close the gap when the bolts are tightened, but I would try to get it changed before installing it.

if he closes the gap by tightening it it will be under unnecessary stress that might cause a crack in the header at a later time.
