Lainaus tuoteluettelosta:
"You will also note that ARP offers specially undercut studs for several engines. This procedure (done only to the shorter
studs) more equalizes the “stretch” of both studs, which makes for a more consistent clamping force – and one that compensates
for head gasket compression when the cylinder heads are installed. This helps prevent blown head gaskets, and assures optimum
engine sealing!"
