How exactly will the springs chew the head up?
While I have not experienced it first-hand with SR motors, i have had this 'phenomenon' happen quite often on b-series hondas that i've built with all supposed 'top of the line' components and JUN step 3 cams, or toda step b cams. the cars made incredible power, and then would begin leaking at the valve seats. apon pulling everything apart, the stock valves would just begin to beat the hell out of the valve seats until it was no longer seating perfectly.
the powerbands were not indicative of valve float, usually the torque will fall off somewhat significantly if they are indeed floating.
it's pretty awesome that you guys haven't had any problems with it yet, but at the same time i don't know of the total miles or runtime your engines have seen when compared to the average daily driven street car that gets about 200 miles per week put on it combined with events at high rpm once or twice a month.
only time will tell, but either way, these springs are retarded stiff, a definite improvement in what I was previously using, and I'm excited to run them in my car.
