918s or crane duals for TR230?
I'm also running the 918 springs with my TR230 cam, but if I ever get heads, I might cinsider the crane double springs. I've heard good things about them so far
) for the doubles then why not get them. same with the double timing chain. piece of mind is worth a few extra dollars. with that said i was running rev duals but im switching to manley singles.
