Here's a tutorial showing the procedures to prevent "fraggin" a flat tappet camshaft....

In today's world, it makes little sense to jump through all the hoops to use flat tappets, when for just a little more dough, you can install rollers and forget about it. There may be better deals around, but Competition Products sells a set of Howards retrofit hydraulic roller lifters and a roller cam for about $600. Add a Howards composite distributor gear for about $100 and you're done. No worries, no headaches and much better performance due to the increased "area under curve" of the roller cam.
i would agree in principle, but what, exactly, would be needed to be done to a gen 1 SBC to convert it over to roller lifters?
