w2 intake on LA

wardy, not to steal Your thunder :D,

The corners are an exact fit, --- a given --- re-aligning holes--- easy!

My question is to the Manifolds makeup.

Viewing the pics, (read machined surfaces ), looks to my humble
eye like a lot of magnesium is present in that casting.

mechanical alignment = professional welder, one whom knows the
metallurgy --- so the damn thing won't crack down the road...

Apologies, not trying to be an *** Sir.
