ARP head bolts

[timsz]

Can someone help me? I need head bolts for my car. I see ARP bolts listed A12 and A14. What's the difference? The A12 is part no. 202-4202. The A14 is 202-4203. I've also seen to use 202-4206. I've searched and I tried to contact ARP by E-mail and phone with no luck. I have a F-54 block. Thank you, TimsZ

202-4206 is the ARP head stud kit you need for the L24/26/28 head. The kits you mention are for the A12 and A14 engines. Look under Nissan on Arp's site to find the 202-4206 kit.
