Default 305E Valve covers on a 305A engine?
Guys I have a set of plaid valve covers off a 63 GMC 305E that I want to install on my 1960 305A engine; I have no issue with them fitting, but I see that the 305A's stock valve covers each have a hole and oil breather cap where the plaid 305E covers only have one side with an oil cap hole.

Question: what will the effect be on the 305A if one side of the engine no longer has a breather cap after I install the 305E covers? Any? it was engineered that way for a reason - I just do not want to hinder its ability to breathe and hurt the already meager performance of the 305A

Assuming there is no issue with having only one breather on a 305A, would it make any difference whatsoever which side of the engine I put the cover with the hole on? On one side the hole would be toward the front and on the other side the hole would be towards the back, so aside from it being easier or harder to reach the hole to add oil, is there a "breathing" benefit to the engine if I put that cover on one side over the other?
