Eagle SIR6123CB rods differences from stock oiling

One school of thought is to limit the amount of oil slinging around in the engine so it can't make it past the rings and shorten catalytic converter life. The other is, with the downward trend in zddp levels in some oil, the more oil slung up on the cam the better. Most new engines don't have the oil squirters for reason 1. On a street or truck engine, especially one that may idle for extended periods of time, I think reason 2 is valid. I've notched some replacement rod shells which is no big deal.
