Hello again,
Here with a question somewhat relevant to my build... although probably a fairly simple one.
I'd like to rev my B20 past 6000 rpm at some point in the future, and I figure that I'm going to have to ditch the stock valve springs if I want even a hope of achieving that.
So that brings me to IPD double springs (which I think are from Iske?), and their retainers. The two choices seem to be the black steel ones, or the fancy gold aluminum (aluminium?) ones.

Does anyone have any experience with these? Which would be better for a regular street build?
