What you really need to do is get springs to suit the cams you were planning on useing. There is no point having springs that are rated to much higger than your cams, they will just require more power to lift them than is necessary. The stock Springs are fine with a stock cam and redline, after that speak to your engine builder as to what springs will work best for you.
Stock -222 cams
I have a bit lighter exhaust valves. 8mm stem vs. 8.5mm
Stock intake valves
The engine is going to be turboed
Now with these facts in the equation.. got any more tips?
I got the advice in the www.fintoys.net forum that I could run 2T-GEU inner springs in conjuction with -222 springs, if I'd want more spring pressure.
The positive pressure on the intake side, is that something I have to consider, or is the effect negligible small?
I have to try to stay with springs available (if available heh) from toyota, otherwise my enginebuilder is going to charge me an arm & a leg. I'm a newbie at these kind of things so all help is appreciated.

There is no better way of putting it. If you are going to run stock cams then run the springs that correspond to the particular grind. Or, use the cams and springs from the head that already runs double valve springs. If you are getting your cams welded and re-ground to better suit the turbo then get the person/company who regrinds the cams to specify the correct springs.
