light weight valve train for quick response? 2?'s 1.)Will a lighter valve train provide a faster rev up and then back down? (a quick response inboth directions in the rev). 2.) If so where do i get the lightest valvetrain parts and what are they made of?

No. Depending on the engine, GM.

Re: light weight valve train for quick response? 2?'s Leanne,
I assume that you are wondering about the purpose of lightweight valvetrain parts. A lighter valvetrain will allow your engine to rev higher if your engine is strong enough to rev higher without breaking. The purpose of revving higher is higher power. Lightweight valvetrain components help the valves follow the cam profile at high engine speed. At very rpm valves tend to stay open, a condition called 'valve float'. Lightweight valvetrain components are very expensive - '02 LS6 hollow-stem valves are $40 each. The total cost of 16 LS6 valves, springs, and seals is over $900. Titanium valves are lighter than steel valves but are super expensive. I hope this helps.

Re: light weight valve train for quick response? 2?'s well, where do i get titanium valve train,(all of it),? Assuming that all of the parts being titanium would be MUCH lighter and more strong than the steel, and what kind of price tag would you expect from that? Would you just reccomend getting LS6 heads (02') and just leaving it at that?

Re: light weight valve train for quick response? 2?'s Manley makes titanium valves but you should be aware that titanium valves are only appropriate for all-out racing engines. My car is a daily driver. I wanted the lightweight '02 valves and decided to purchase the complete LS6 head assembly. The complete assembly is significantly cheaper than buying the parts individually. The part number for one LS6 cylinder head with valves and springs is 12564824. They are listed on the GMPP web site. I found the best price at Pace.

Re: light weight valve train for quick response? 2?'s Leanne, you should consider whether you want to purchase GM part number 88958622 instead of the stock LS6 heads. For a few hundred extra bucks, this other part includes the '02 lightweight valves but the head is CNC ported and with the right cam could produce much more power. As I said, my choice was the stock LS6 heads but there are other choices.
