Are the supertechs dual springs? I'm not a head guru at all, but I always thought dual springs increased the pressure quite a bit, to the point I personally don't want to run them on a car I put a lot of miles on as I'd imagine that large increase in pressure would start to affect other things like valve seats and what-not. Would rather just run upgraded basic single springs, or beehive single springs if I needed something more than that.

But again, I'm no expert on that type of stuff so maybe I'm way off.
