How Fast with Hydralic Cam at the Strip

does a hydraulic roller count? My Valiant with 408SB runs 10.70 with a comp custom HR, 250° @ .050", .620" Lift with 1.6 Rockers using the stock mopar HR Lifters. I put some more power into it 2021 (this new cam and 1 7/8" headers), the converter now slips a little more a the top end - around 6700 rpm going trough the traps without any trouble. I´m thinking about getting a more serious cylinder head, see no problem in keeping the HR cam for me - even with a little longer duration.
