Crossover coolant tube(Not sure what to call it)

I think the 4 corner was made to accommodate engines sitting at near zero degrees like the corvette . 4 corner vent would be a must in this situation . The rear could develop an air pocket and create a hot spot . Also a must in a swap sitting close to zero degrees as well . Most swaps are at least 3 degrees or more and would not necessarily need the 4 corner . The air would migrate to the front steam vents anyway . Thats why everyone says never had a problem with just the front vents only ( including me ) . It is doing what its supposed to at those engine angles .

Add it if you must , but if the engine angle is a 3 degrees or more it will not be necessary .
