[QUOTE="footlong70, post: 1332218, member: 8456"] Studs one at a time is very reliable if done right. Oem bolt torque/initial seal means squat when you double/triple the clamping force with studs, further crushing the gasket. Head gaskets can even be reused if you read some of the old mechanic books, as long as more clamping force(higher bolt torque value) is used and no damage to the gasket. Head gasket technology for the most part hasn't really changed much. However nobody in their right mind does the major job of pulling the heads (magnaflux/machining/cleaning/ect)and takes the chance of putting a used gasket back on that might be compromised even a little during the head job anymore. Doing the studs one at a time I don't consider a major job. IMO, if the gaskets are not already compromised, the gaskets are the most updated oem, the clamping force of MORE than ONE bolt/stud doesn't go below original clamping force, and the sequence is utilized than I firmly believe you're in the clear. With oem updated head gaskets being able to handle +1000hp with enough crush force over oem clamping force, I don't see the issue. The biggest concern though is not trying to band-aid head gaskets that puked before. Ive run mine zero issues for a little over a year. A lot of heavy mountain towing, racing, 60 PSI boost, ect. Very happy with it. [/QUOTE]
