Fitting TTi headers on a 273

What about slotting the bolt holes to the low side and pulling the header UP slightly when installing. That distance to cover for a decent sealing edge may be a reach on this one. Is that a possibility instead of welding on them or making a plate.

Jig that in a mill and be done in quick fashion. Or hillbilly it with a dremel or drill...

There have been issues before with tti and ported heads as well where the sealing surfaces are not close to each other. Only option was to tig them up and mill the surface.
