hi , I did a compression test on a 350 chevy , here is what I got (1)180 (3)175 (5)180 (7)175 psi other side (2)170 (4)165 (6)165 (8)162. engine runs and sounds uneven and is very rich as spark plugs are black . there no water in the oil but can see water drops up top of the valve covers. is this a blown head gasket or something more.:(
