Hey guys, need some input on me running stock lifters with 30,000 miles on them to 7000RPM with PRC double springs? Let me know, thanks.

I put my cam in at 110k and used PRC doubles. Stock lifters, now at 118k. They tick like hell, but most cammed ls1s do anyways. My rev limiter is 6800 shifts at 6500 though.

Dlove is a mod on here and a local guy in my area. He spins his to around 7200-7300 with ls7 lifters. I use them. Havent had any issues

So you guys are saying I should be good to go right? I hear all LSx engines have LS7 lifters already..any truth to that? My motor is a 05 LQ4 so is there any chance I have updated lifters? I have the heads off now so I could just look at them if there was a part number on them or something. Someone please enlighten me

The LS7 lifters are not anything special. The same lifters are used in the other LS based engines.
