| So Im contemplating the ARP head studs. John at Z1 says he recommends them for high horsepower cars. Im going with the Sport 535s but I dont plan on turning up the boost alot (especially since im still on stock ICs). Id like to hear some thoughts as to whether I should get the ARPs simply for piece of mind that my engine will be more enduring at ~400rwhp. Checked SEARCH, nothing specific enough. Thanks in advance Josh
