i ordered some b18c head bolts from topline performance, they told me they were made by arp and i only paid 45 shipped, they look legit when i got them but the box said b16a2, will these head studs work on a gsr motor, i know the gsr's are supposedly longer but some have said they work, but these are from people i dont really trust. can anyone help me out so i can return these before the refund period expires

 

return em and get the right ones

 

b16 studs are shorter. you need the gsr studs.
