Thanks for the input all.

I am going with the second (softer) set because that is what my gut says and its what most ppl have suggested in this thread, no doubt the stiffer spring would be as good but I don't think it gives any added benefit in my application, maybe with some cam that has shorter duration, possibly better on 16ve regular cams.

I went with the first set on my big turbo setup for one i had initially planned to rev to 10k plus and two better sealing under big boost. I too am using n1 cams and have taken the motor past 10k. Also on stock valves and had no issues with valvetrain.



what would be considered big boost? or hp rating for the 130s? just curious whats the turning point from the 100 to 130 (whats needed)

I just went with them for the little bit extra security. Most people use the 100 lb seat pressure springs. However most of the guys are n/a as well.

I had planned to run 40psi of boost so you have to account that there is going to be 40 psi on the top side of the valve. Again my own personal choice and added security to prevent any pressure leakage from the valve area and for the high rpm that i was going to be revving to.

i was thinking anything over 25 psi would be the turning point, did you have to machine ur seats for the 130?

No, I understand thats what it says on mazworx site but its just as drop in and go as the 100 lb seat pressure springs.

No issues at all with the valvetrain and again it saw 10,200 rpm during a pass and 9800 rpm before that on the dyno and other passes.
