Header Interference?

Yep, it’s tight in that engine bay when it comes to hedders.
I have 1.03 torsion bars which makes those clearances even tighter.
Sometimes I think about mounting the motor solid since about everything else shifts position after awhile.
Just can’t bring myself to do it.
and that's why I'm retaining my factory 340 '69 cast iron manifolds when I go to the MP 1.14's
