    I'm putting my heads back on my engine and it turns out I lost one nut when I took the heads off. I went ahead and ordered another nut from Summit but apparently I got the wrong thread count. I figured it would just the fine thread 7/16-20 since ARP's website didn't show any finer thread 7/16 nuts. Anyone have any clue what nut I need? A part number would be sweet if anyone has it. BTW, it's a 12-point nut I need due to the big valve springs on the AFR 210s. I hope the local speed shop has something I can use tomorrow!
