No problem with the bandwidth. Your questions are all reasonable and concise. 
This is why we're all here.  

Early engines used no O-rings here at all. I believe the O-rings were 
introduced around '66, but don't take my word for this. I know they were there 
by '68. The instructions for rebuilding early engines were to countersink the 
holes in the right case halves (the ones without the studs.) If these 
countersinks were made just a bit bigger than the double countersinks in the 
late cases then the same O-rings would work there. 

You have to make sure that there is sufficient room in the countersink for the 
O-ring to be completely pressed in there, otherwise this will hold the case 
halves apart, which would lead to disaster.

OTOH, I'm sure that LOTs of such engines have also been rebuilt just as they 
originally came, with NO O-rings.
