Radiator Installation

[Zombie666]

I have a Holley Frostbite 3 core radiator for my LS3. At the moment I have a set of gloves between he rad and the lower support. I will replace with appropriate rubber isolator but for the moment I'm not happy about how high the rad sit still in the core support. Is it normal for the rad to sit about 3/8" higher than the top of the core support. Am I missing something?

Thanks in advance
