  • Valve train guru's needed

    I have a 02 ws6 with 11,000 miles. It doesn't see a lot of miles on it but I want do things right the first.I put a Texas Speed Torquer v2. cam in about six months ago. Awsome cam 400 to the wheels. I am now putting their stage 2.5 ls6 heads on with yella terra shaft roller rockers. Now my question is since I'm adding weight at the rockers and with the valve being bigger in the head would it be smart to go with a titainium retainer. Now the current 918's with the stock retianer are fine up to 6800 with no issues. Also Iv'e been told from alot of performance mechanics and they say their are to many breakage issues and pressure on valve guides from double springs. Any advice would be hepfull.

    Cant hurt, id go with a dual spring though, PRC gold, or PRC dual platinums. IIRC there the same thing.

      the roller rockers will take the side load of the guides but the swipe pattern should still be checked.
      I would get some patriot or PRC dual golds. much better spring and the safety of a dual

        Thats the route I am toying with. Patriot dual with titainium retainers. If this seems to be the general consensus then this is way I will go. Thank for all of your input.

          Not to doubt you but why are you using YT's? Stock rockers are good to over 7,000RPM. Most of the time you only see guys going with aftermarket rockers when they are necessary like when running aftermarket casting heads such as TFS or ETP's.

            like i said. the stock rockers work but the rollers are better. depending on which he is gettting they are also adjustable.
            if you ask tfs and others they dont want you using anything but roller tips anyway

              Well of course rollers are better. What I'm saying is I don't think they are necessary with stock GM casting heads. Money could be better spent else ware at this point IMO.

                well in regards to why use the roller tips on stock casting. Mainly for a more queit valve train. And of course any reduced friction is a plus.

                  Well thats understandable. If you have the money why not spend it!

                    Well it's decided. I went with prc duals with titan. retainers. I intalled them today and mounted the heads snugged the bolts down. I dind't start the torque sequence today for time reasons. Never walk away from a torque sequence. I've seen some expensive redues from poor reassembly.Should have everything wrapped up in a couple of days and keep everyone abreast. Thanks for the push in the right direction.

                      TFS require aftermarket due to geometry. You don't have an option with them.

                      Also beehive springs are much better for controlling the valvetrain, PAC 1518 would be good. Premium lightweight nitrided valve spring. You guys are worried about retainers when the spring is the issue. I'd run a PAC 1518 and titanium reatiner if you want. Be fine for all the rpm you can give it.

                        Iv'e been thinking on the debate on OEM LS rockers and aftermarket rollers. And I believe that factory rockers are not a supperior design. Althout they are the lightest rocker arm out thers is always a certian amout of flex in factory pieces. The other reason for aftermarket rocker is thier design is to be stronger. Now weather you need it or not minumizing structural weakness can only mean a more accurate cam lift transfer. In my humble opinion of course.
