You are building an ls/vtec with factory ls rod bolts....?

All its going to take is a over revving insident to strech your factory ls rod bolts & spin a bearing...

You may get lucky & be able to get away with factory ls rod bolts, but I do NOT recommend it.

Arp rod bolts are a pain in the ass to have installed properly (take your rods to a machnist wich has done them or has a rod bolt streching tool as the arp rod bolt instructions instruct you to do so etc..)

Arp head studs are not gonna do shit for ya except allow you to re-use them if you ever have to take your head off... (they supposedly do not strech)
