Don't like hydraulic anything. Don't like the roller solids, all though if you spend ENOUGH money you can get a MODERN set up that works OK. This assumes you DO have the right kind of block to work with. Some side oiler blocks will NOT support a MODERN roller design OR hydraulic lifters of any kind! Flat tappet is your ONLY logical choice for any street application.

Besides, for good performance at a decent price it's hard to beat the flat tappet design.

Been there, broke that, no more solid rollers for me!
