What's everyone using for roller lifters? I am looking to get new lifters and boring my lifter bores out to fit the .904 lifters on my BBC dart block. With everything out there and all the options I can get what would you guys recommend. I have used Crower in the past but am not going with them anymore since they don't rebuild there lifters anymore. I am looking at the isky redzone lifters and am steering toward them, but is there something better? Let me know.
