I have tried the old trick with rope seals that you use with the rubber seals by rotating the upper and lower sections so the end are 10° to 15° past the parting line of the main caps. I had never had any leaks with rope seals before this anyway, but I just wanted to see if this added an extra measure of leak prevention. It worked great as well. I've also used that trick on other engines that use rope seals also, like several Pontiac V8's with no problems either. This may add an extra measure of prevention if you want to try it too.
