What kind of valve springs does our V6's have? Are there any aftermarket springs we can get like titanium or something like that?

 

BrianK's the man with the info on this.. but I don't think we need titanium springs. If I ever got 'em, I'd get see-thru valve covers!

 

105# you want with 1.52 roller tips or 1.6's... Never add new rockers on stock springs.
