Dougs 453 headers with 727?

I've got Dougs with a 318 and an A518. No issues at all with the transmission.
Problem areas are torsion bars and possible steering column on tube no 7.

If you drive your car on salty winter roads, forget about the ceramic coating. It'll be gone near the lower tubes and collectors in just one winter.
Top side stays nice though.
