Mechanical roller lifters, solid. (Pin oilers?)
Just so you know usally the more money you spend on lifters the more options go into them , We personally use Moral , Howards, or Iskys , on all of our street style solid rollers we get the lifters with neddle bearings in the rollers also we get them with pin oiling , he also grove the lifter bores , this helps provide extra slosh to the cam and lifter roller plus gives some extra cooling oil to both . When roller motors fail it usally take the hoke motor with it , so any extra money or help in this peticular area is money well spent . IMO .
