LA top end rebuild question

Oldmanmopar, could you go through the process of measuring to get the perfect gear size for the timing chain, right now I'm running a Cloyes true roller with a tensioner. Right now my engine is apart, re-ring, bearings, cylinder hone and deck, was just going to replace cam and heads! The Tensioner worked fine, no wear and kept good time, it has been on for about 8000 miles. It's a 52000 mile 340.
