what is the specs of your cam?

i had the same question in my mind, but since i have a cam with a lift of .621 then i opted for the full roller rocker, and glad i did. not only is the drivetrain more stable (in my opinion) the motor is 10 times quieter then it was before!

The problem with roller rockers that do not cost 1k or more is they have a lot of nose weight over the tip of the valve, making the valve train un stable at high rpm's and cause valve float.

The stock rockers are light, strong and with the trunion upgrade, they are perfect for 99% of all builds.

The only thing that worrys me is that I have trickflows with bronze guides and they(trickflow) recomend yella terras or harlan sharps.It just seems like the full roller would be best,but several people have said the stock rockers with trunion upgrade would work fine even at 600 lift.

In addition to lift you also need to consider the open spring pressure of whatever valve spring you will be running. For example, neither OEM rockers nor the Yella Terras are reliable when used with valve springs with more than about 400 pounds of open spring pressure. So, if you need high-pressure springs you will need more expensive rockers (e.g. Jesels, or Comp 1500s).

Dont run stock rockers with bronze guides... It will kill the guide.. either pull the heads and get powder metal guides or buy roller rockers... Plain and simple

Are you talking if the lift is over a certain amount - like 0.550 on stock LS6? What do the stock LS1 & LS6 heads have for valve guide material?

stock are powdered metal, much more wear resistant, that is why 1nast86 mentioned the option of having powdered metal guides put in aftermarket heads

Yes sir! Exactly what I was going to say! The Trunion Kit is a great way to go IF you use the powder metal guides. Feel free to give us a call or shoot me a PM with any more questions!
