So im fixing to order a new set of lifters, just some basic hydraulic lifters. Will their be any noticeable difference between the Rhoads variable duration ones ($90), Comp high energy ($90), or just the summit racing ones ($60). Are they all basically the same? If the Rhoads will give any extra performance and their variable duration isn't pure BS, ill go for those. But is there any difference between the comp and summit ones besides the name?
