Hey guys i need a new set of head bolts/studs for my b18. Without getting to into the explanation heres my question. whats the difference between the LS head studs and the GSR Head Studs and the LS/VTEC head studs that ARP makes in terms of length and thread.

 

bump....can someone at least tell me if the head studs you should use belong to the head or the block? ex: ls studs for ls ehad or gsr studs for gsr head regardless of the block.

 

LS set has to long studs for the center holes.

GSR studs are for GSR/B16 head and B18C1 or B18C5 bottom end.

 

So the LS set has 2 studs that are longer then the rest? and are the thread sizes the same between LS and GSR?
