there is some controversy on this issue. My opinion and it is mine only, is that the 426 at less than 160hp is good for 4500 hours untill you need to think about this area. On the intercooled versions and preventative rod bolt and rod brg change at 3500 hours is like a good insurance policy. N6 combines are the most at risk... and no you don't have to remove rods. Drop the pan and change bolts and brgs and you need a pan gasket...
