Here's what I'm thinking:

GM racing lifters #88958689
Patriot Gold Performance valve spring kit
Trickflow or Comp Chromemoly Pushrods, Stock 7.400 Length
Yella Terra Shaft Mount Roller Rockers 1.7

Gave a lot of consideration to Comp 918's with ti retainers

I am with you on the lifters and rocker arms...

I went with Comp springs and ti retainers

But be warned about the pushrod length, i am going to be runnin LS6 heads that were milled and trust me, you dont wanna mess up on the length...Measure twice and buy once...

The patriots are at an AWESOME price...250$ for high lift springs with ti retainers, but compcams beehive single spring with ti retainer is less mass bobbin around which will allow you to rev it way up...7250rpm is my guess...

Luke can hook you up with a nice price on the lifters...

Just to give you an example, I changed the pushrods in my Tahoe with new 7.400"...I have had a small shake at cruisin speeds. I brought out the original ones and measured them with a digital caliper...I found them to be 7.345"...Woops. I am going to be changin them out tomorrow, need to get my Tahoe back from the garage.

The LS6 engine have shorter pushrods then LS1s for the reason of the higher valves on the heads. They are 0.6mm higher then normal for they are sodium filled...Higher valves, shorter pushrods. Shorter lifters longer pushrods.

Like i said the before, Measure twice buy once....
