440 lo comp rings worn?

hello, many thanks for the input, a pal has loaned me a leakdown kit so will be doing that monday, also the thought of my timing gear being bit @@@ does also make sense! i will be trying a 650 carb on there as the 750 overfueling, yes this will not help a worn engine but i am sure not help the way it behaves! many thanks again, will keep you posted,nathan.
