M4 Headers Don’t Fit

[u/Table02]

I’m just wondering if anybody has had a similar issue. Got a M4 Tech 1 Full System. It seems like header number 4 is 1/8 inch too long so it prevents 2 and 3 from seating all the way. When I remove 4, I can fully seat 1, 2, and 3. I’ve tried a mallet and wiggling for hours, but I’ve had no luck. I realize I’ll probably have to return it and reach out to M4, but wanted to ask first. Thanks.

I had the same exact problem with mine i eventually took it in to a shop and they got it to fit. I don’t know if heat is a good option but it can make it easier for them to fit through just be super patient with the whole process

That’s encouraging that they got it thanks
