Gen 2 valve springs

[simmo]

Anyone got any info on how heavy you can go on valve springs on titanium valves

Sorry,can't remember exactly Simmo, but I'd ask "Knecum" on the org as I seem to remember seeing that info before as a lot depends on the cams as you probably know.
Cheers,

Yep been looking there, sorted thanks to Leonard & yep more to do with the lift now
