As you mentioned,Gene,a Holley Street Dominator is basically 70's technology. Edelbrock's Performer RPM and Air Gap dual planes will outperform a Victor single plane up to around 7,000 rpm. One of these dual planes would be a very good match for your L98 heads. Just curious but what kind of cam & valvetrain are you running? What kind of revs are you spinning the motor to? Running solid rollers on a pure street car is just asking for trouble. I'm not going to spin my 350 high enough to need them and the need to pull the intake to inspect them for excessive wear every 3-5000 miles isn't worth it to me. With a good matched valvetrain,hydraulic rollers will work very well up to 6,000 rpm or so. That's all my engine combination requires for a daily driver. FWIW,I would be more inclined to run solid flat tappet lifters before solid rollers because I know they would be more reliable. If the hydraulic lifter quality nowadays wasn't so hit & miss,I would definitely prefer them. If the cam deal I'm working on falls through,a Comp or Lunati hyd flat tappet cam will probably be bought.
