Be sure to check end gap at the top & bottom of stroke plus check clearance from ring land & ring. I had a 48 Plymouth sand buggy with a 2″ driveshaft flathead 6 & we put in new rings never checking end gap. It was so tight after warming up it wouldn’t turn over. We had to drag it backwards to free up the rings. WE pulled it down again & corrected end gap. Be careful filing the rings they break essy, I learned.PS hone the cylinders too.
There is no way to tow a kg7 backwards to free the rings.
