Has anyone tried these Summit headers?

Brain, I have used those "1 size fits all" headers before on my '73 Cuda with excellent fit, though, I'd consider myself lucky since there not allways made exactly the same everytime nor is every car body exactly the same.

I have seen mix reviews here @ FABO with these headers. It is a bummer that affordable headers have certain cave eats.

Poor quality control
3 tubes under the steering linkage on the drivers side
The need to ding/dent the header for clearance
etc...

Just do not over tighten the header bolts to the head. The thin flange will warp on the center 2 port causeing the flange to bow and never be able to be sealed up. Just a few foot lbs. is all it needs.
