There may be a difference in gasket brands, but what I have noticed the most is in how long they have been on the shelf. The ones that have been on the shelf a long time seem to not seal as good as a fresh one. My dad used to soak old gaskets (already used ones) in water for a couple of days and then put a thin coat of grease on each side just before installing them. I have seen this work myself as a last resort. I’m not suggesting that you do this rather I offer this for an example of what the effects of long shelf sitting can do.

When I torque heads on engines with studs, I continue the torque pattern until the torque on all the nuts is the same. When I re-torque the head after it has run, I do the same thing with the engine is at operating temperature. Keep at it until the torque stabilizes on each nut and with the engine warm. Metal expands when it is warm, so the studs will stretch when the engine is warm.

Good luck!
