The head gasket has a much smaller hole than the passageway in the block and the head. Is this right? Should I enlarge the hole?
On a side note, I was having cooling problems (not cooling enough) with no determined root cause (yes I know there are many reasons why this could happen). Could this small hole be limiting my coolant flow for no good reason? Why is the hole in the Fel-pro gasket so small?
Thanks in advance.
