very possible.
a bolt clamps something by being under tension.. basically, when you tighten it, you stretch it. that stretch is what keeps the clamping force on the head.
bolts made of different materials or of different thicknesses/lengths, stretch differently.
for example, the GM TTY bolts never shorten to their original length.. they actually stay longer..
the ARP ones however, return to their original length after use... use ARPs specs and retorque the bolts if its alot higher then stock.... i dont know the numbers as ive only used the GM bolts on LS1s...... and they're different for different ARP bolt kits.
