I have the retro hydraulic roller lifters in my small block. I've found that they bleed down pretty easy and will rattle pretty good on startup. If I run 30 weight oil they will have trouble pumping up. I run 40 weight now and when set the lash l'm very careful because the spring load in the lifter is almost zero. I think it's common with these aftermarket roller lifters.
