Thinking of getting a set of drop in 1.8 ratio roller rockers. Will be upgrading pushrods and springs at the same time. So which are the best? Harland Sharpe, Comp Gold, Skorpions, or Yella Terra’s?
Save your money on the rockers ,years back I called Brian Tooley racing ask the same question , He said they at B.Tooley racing had Ls motors making 700+ hp with stock rockers , just install the Trunnion kit . He told me the stock rockers are very light they use them so I did and am very happy ..My 04 makes 550 HP ..
Engine Masters on youtube has a comparison of rocker arms. They are stud mounted rockers but its worth watching if you are considering swapping yours out.

Really good episode. They showed a 17 HP increase and 2-3 Lb-Ft tq increase going from 1.5 to 1.6 ratio. That would be about 13 - 14 WHP. Not too bad for not a lot of work.
Seems like either the Harland Sharps or Yella Terra is the way to go. Will upgrade springs to PAC 1219x and get hardened pushrods. May also get titanium retainers to lighten things up.
