A stock regrind would probably cost more than its worth. If you want something mild, the Integral Stage 1s should do fine.
Aren't Corksports basically JayDeeEm? Those really don't make that much more power...
And when it comes to cams, if you want to play, you've got to pay... anything that will make a worthwhile amount of power over stock will compromise your idle a bit. With camgears and my 02 sensors plugged in, my car actually idled on Integral 2s (they barely idled with the 2s in stock position) and still made 10-15 whp more at redline.
But again, as I've said in the thread I made... they really suck at low rpms... so a set of stage 1s or a stage 2-1 combo would probably be better for a mostly stock engine with a stock redline.
