I have posted this more than once.When Comp came out with their hyd roller cams I ordered a cam and kit for a RA V build.After getting it I called Comp and asked if they were OK with their lifters at 6000 to 6500.They called me back and asked me to send the kit back and they replaced them with solid rollers and springs and wanted 200 on the seats with 600 open and set at 6 thou.I have run the hybrid for more than 15 years.Now with the hyd roller lifters being proven at more than 7000 I have changed to their lifters.Have my last 3 engines with them and just ordered a set to replace the solids in my 421 SD engine.My last build made HP to close to 7000.For a hipo street engine I no longer see the need for the hybrid setup.Again I run higher spring pressures.Comp told me no issues with 180. FWIW,Tom
