I use the isky Red Zone EZ Max bushed lifters. They don't use a bronze bushing. I have ruined three of my Street Motors using needle bearing roller lifters.
How much spring pressure do you run on the street? How much driving do you do on the street?
On mine I am about 260 seat 785 open. I drive only a couple thousand miles a year.....
If you need almost 800#s open pressure, you're probably not running a cam that I would consider for a "street motor". No wonder your lifters didn't hold up.
Yeah, you drive it on the street, but you're not really building it with any realistic expectations of longer-term durability.
