Thanks for the input!

I bolted headers into a spare head and heated a red band around each tube ....not sure how hot to get tubes to relax them.

they are pretty true now.

I am thinking of braze welding a "D" shaped plug in edge of oval ports since my head ports are rectangular and gaskets don't fit that well. I don't expect the header metal to ever exceed bronze melting point (I'm guessing 1700F... I will check it). I am running 351W at less than 365HP. On second thought I will probably tack "D" plug with Mig then fill in with bronze.
