another thing to consider is what year intake and heads you are using. Basiclly both sides of the valve covers have to be vented, some use PCV valves, and some are vented through the oil filler cap. Later 60s stye routed vented crank case air through the carb or intake for emissions proposes. I think if you have a spacer a hose would have to be connected or plugged you would have a big vacuum leak at that point. usually both sides of the heads are vented, but depends on the year and intake and heads you are using. Maybe you'll get more of a specific answer than this. |
