Hard to beat a hyd roller for all around power, no wear issues etc USE THE MOREL lifters NOT the Comp Cams versions--for sure if you get a flat tappet to live --it is a lot less $$$$$ and will make excellent power--solid roller takes more spring pressure--OK for drag but you really have to watch pressure on street units as the cycles add up quick and wear out lifter bearing axles fast---
Best all round choice if $$ is not an issue is a hyd roller--Power, good vacuum, quiet ( one turn preload on the Morels and its quiet as a mouse peeing on a ball of cotton)
