Question 1: General note #M3 states one piece seamless heads. Can two pieces be used if seam is 100% R. (X-Ray)?

Answer 1: A two piece head that is 100% R (X-Ray) is not acceptable. Head must be one piece (seamless) as stated in the general note #M3.

Question 2: Dwg. M-1480 Sheet 24. The entire header would need to be installed before the head is put on. It would facilitate installation and/ or future removal of the header if there was an internal flange. This would also facilitate the hydro-testing of the header.
