Not being a true Enfield man I confess to not knowing the answer. Somebody will be along soon to answer your question.
However your question raises another fundamantal question or two. If the big end bolts have worked loose as you say, then how did that happen? Have you recently rebuilt the engine and if so did you re-use the original boltes? If you did then that is why they have come loose.
What damage has been done to the crank pin?
These are all far more important IMHO than trying to avoid a full strip down.
Are you intending to retighten the bolts? If you are then DON'T.
Big end bolts should be tightened with a torque wrench. They are designed to stretch by a fixed amount when torqued up during the tightening process to maximise their effectiveness in a very highly streesed situation. They do not recover when loosened and any subsequent retorquing will undoubtedly cause a catastrophic failure of one or more bolts with subsequent and equally catastrophic damage to your engine.
Assuming you have plain metal big ends then strip them, check the journals for size and damage, regring or replace if necessary. Fit new shells and most definitely fit NEW BOLTS.
