Regarding valvespring tension
Hello! I'm wondering how stiff valvesprings that will be optimal for my GTV6 2.5 engine. I'm having 282-degree duration cams with 11,4mm lift, thinking of reving max 8500rpm.

Help: Titanium valvespring retainers
Hi!
I have a vague memory of someone selling titanium valvespring retainers, but I can't seem to find the post anywhere! Have I dreamt this?
Please post the link if you know what I'm looking for.
Also, if someone tried it, tell me why and what you think. Also tell me why I should not use them.
