Actually I did. Todays oil is just fine. Roller tappets weren't designed for better wear characteristics, they came about due to the need to follow steeper profiles. With advances in cam profiling flat tappets now enjoy pretty fast opening ramps. Think about how much force bears down on the tappets. Now compare how much contact area bears all that force is on rollers vs. flat tappets. Rollers have very little area bearling the load. Honestly, with today's oil I'ld expect a good flat tappet cam to last >100,000 miles, especially if he keeps the spring pressure in line with a street engine that won't be hitting 7000rpm. Also don't forget that materials and quality control on cams and lifters are considerably better than yesteryear.

Now for the single plane intakes. Yeah, conventional wisdom does say it's not as streetable as a dual plane, but real experience says something different. As a matter of fact, that "wisdom" probably comes from those small block folks. A big block generates a great signal to the carb at the beginning of each stroke due to the large cylinder cross-section. I've been using single planes on the street many years and never found them to be even slightly non-streetable, and they kick butt!
