Valve spring question I'm setting up a LQ4 with LSA heads and a ZL1 TVS1900 blower (2.55 pulley)
deciding between the GT2-3 or LS9 camshaft.
i've been told LS9 springs are meant for the titanium valves that i dont have.
plus the added boost might not make them strong enough.
what would be the best and most reliable valve springs?
for use in a daily that will get LOTS of highway miles.

I prefer beehive springs. I would recommend the PSI ML 1511 spring. They are arguably the most reliable beehive spring and are rated to .625. I like them because they are simple and not overkill. I didn't want any more stress on my valvetrain than necessary so that's what I used.
