How much spring load will the LS7 lifters take?
So i just got some new AFR 1040s that were ordered with the AFR-8002 springs and i have been told they might be to much for a hydraulic lifter unless i spend a grip and get something like Morel lifters. I dont really want to pull the springs and get others since everythin is setup and brand new now. These will be goin on a built 356 with a 224-230 .57s lift cam. The motor now has a smaller comp cam with im guessing comp cams lifters....anyone know if the lifters i have will work fine? If not what should i do...i have been told i maybe could run the LS7 lifters?

I bought the heads off a member on another forum and they were opdered with the better springs vs the 8017s they come with. I got them for a killer deal and i could nto pass them up. I have had people tell me i can run LS7 lifters and call t good and now have had people tell me it might to to much pressure for a cast cam

Did they cut that pocket for that larger diameter and make the cut extra deep to get that extra installed height, or are they running a long valve? I agree, as long as you have them at that taller height, they look fine.
