Default Re: boosting compression? ideas?

explain that too me, where is the back pressure needed?

I cant bring myself to get one over a shift kit, I just do not care for the look of them even if they are such an improvement. id love to build a motor for best power, though I seriously doubt the bottom end integrity of these motors.
