Yeah, I was checking all that out. The all aluminum looks awesome, but I really need function over form. "MAX" has never had an overheating problem. Just a small crack that seeps coolant. I just want oem. Nothing fancy. I just don't know if one or two rows makes a diff. The first page on ebay when you look them up is full of both types. And they're all about $70. Is that too cheap. I don't know. Just want OEM equivalent or better.
