Keep all the bolts loose till you get all of them in. If the holes dont line up you have 2 options call and have the header replaced or stock manifolds again you cant cross thread them or go without. The dip sticks suck but it will go in just take your time. And try torquing the bolts on the y pipe. You can use sealants but they never last. Make sure both flanges are not coated in carbon before they go together and check the y pipe for rust
