I've got a 408 Lq9 on its way. So I need head bolts. Going with ARPs but I keep hearing about different legths for 04+ and 03-. I'm using 243s so I assume I need the 03-.

Part number would be great but so direction is good too. Thx

 

Never mind I found the ones I needed. They were the 04+ arp 3610s
