7.3 to a 460 Big Block swap??

Hi, its been awhile since I posted.I had some truck issues.I blew the head gasket on my 7.3 .I am afraid if I just replace the gasket and not Fire ring the heads it will happen again. It seems it is going to be pretty expensive for the work on the 7.3 heads.I assume to much boost? I am thinking about selling the motor and going BIG BLOCK for the mud races.Something faster off the line.My question is I have a brand new BTS tranny E4OD with a PCS controller what do I need to change for the big block to still run this tranny? And I will have some parts or whole motor for sale in the near future maybe.It still runs now just builds pressure instantly. Any advise would be helpful.

Advanced adapters makes one to i beleive. Like slowleak said though, where your at power wise i would think it would be alot cheaper to stud your engine rather than building and swapping in a big block.
