i have a 2000 M6 Z28 LS1 camaro. i was told that the Yella Terra
non-adjustable roller rockers are better than Harland non-adjustable roller rockers in terms of performance (maybe because the Yella Terra rockers are lighter than Harland rockers) .

my question is are the Yella Terra rockers that each two rockers are tied toghether as the Harland rockers?

any one one can provide pics for Yella Terra rockers (showing each 2 rockers are tied together) for the LS1 engine?

thanks.

Yes they are.

Why use aftermarker roller non-adjustable rockers on an LS engine when the stock non-roller rockers are stiffer, lighter, have a lower Moment Of Inertia (MOI) and are cheaper even with the rebearing mod by HS? Roller rockers require more valve spring to control the system just because they are heavier, less stiff and have a higher MOI. They really need stiffer pushrods also, but that a good idea for any LS engine.

Roller tips are not necessarily better than non-roller tips. There are LS engines twisting 7800+ with stock rockers and HR cams, and living long lives.

My $.02.

i like the stock rocker myself, but some heads require you use an aftermarket rocker.

thanks for the replies and thanks for the pic.

i will go with 1.7 Yella Terra non-adjustable roller rockers because i have a touched up TFS LS1 215cc heads from Raymac Racing engines that i want to install later and they need roller rockers to be used with them.
