What Roller rockers work best
So I’m running a cam on my LS7with a bigger lift .667 and I’m looking into getting roller rockers I’m running a brodix heads with PSI 1513 springs, Bronze valve guides and I can’t remember what valves are in the head but what rockers would be best for my set up

I’m using these and have worked really well:
…another perk, I run Brodix heads as well…ls7 small bore that GPI works over and I can even use stock valve cover.

Work best, or last the longest?
Bronze bushing rollers work well, don't have to fear of roller bearing coming out and into the motor, but Bronze bushing is not going to last as long as needle bearing roller.
Also, are we talking stock lift height rockers, or is the intent to go with higher ratio rockers, so roller lifters are being lifted less to not wear out the plastic lifter trays as fast.
Bottom line, radical cam, valve springs need to be changed every 30K, before they snap and cause problems,
and when doing such, do you want to just rebuild the lifters as well, or have to replace them if not rebuild able isntead.
