My rear crossmember did not need any mods. I’ll attach a pic at the bottom where you can see. I used the TTI measurements to set mine in place and the headers fit perfect. It looks like you’re using the same black as I have for the MC. Not sure what heads you’re using or valve covers but I moved my MC mounting studs up 3/8” and I needed that extra space. Now my offset block is tight against the body ledge that is above the MC on the firewall.

You can see the crossmember on the one side and the mount stud sticking through

I used these measurements, which worked out.
