I have the Steens in stock----USA made--super quality--good as Comps if not way better $375 set yea you can't Google them--they keep low profile and just keep on making some of the best private label parts ever--
Good to 650 open easy as pie want 750 and up on open--( you lifter killer you) go with some bushed Morels and pay out the y8ing yang OR...run reasonable lower pressures than are asked for by the crazy computer designed lobe crowd--run a reasonable lobe and get by with less $$$ lifters or...pay $900 for lifters run 1000 lbs open and still loose that bracket race round by .003
These days the newest lobes "require" stupid spring pressures you are probably not in a COMP Eliminator class turning 11K RPM so ...
Keep it reasonable--keep it in one piece--keep $$ under control
Stay away from Johnsons ( labeled as many names you know)
Steens are way cool lifters for the dough
