not near you so i cant send you to one, but any engine shop can hot tank and check the block for leaks, these engines are not rocket motors, the hardest part of the rebuild is butt grinding the valves to set the clearance, but you can(heaven forbid) use adjustables for that, its a cast iron block and machined like any other block, leave a message for ken ct on here, start a new thread saying ATTENTION KEN CT he lives in ct and does the carbs for flatheads, i know he will be able to send you to some one close, tell him what you need
