You'll need to raise the inners almost to the top of the hood, and possibly tub the firewall to run 22s. If you want to keep the factory inners you can, but it'll require a lot of work and won't look factory anyway because you have to relocate a bunch of stuff. Trailer fenders are easier and unless you're doing all the fab yourself, cheaper.I know the rear takes a lot more but I'm ls swapping it and when the front end is apart I'm doing all I can to get it ready for future projects
