I purchased ARP Head bolts this week and I was unknowingly given Ram Air Bolt vs standard head bolts. 6 of the 12 were about a 1/4" longer. I used them and torqed them down. I made the bad asumption that they were correct. and used the longer ones under the valve cover. I discovered the next day that they were the wrong bolts - does anyone know if this is ok or have made a huge mistake?
