You guys got way off base. According to an old ('98) ipd parts flyer, the K grind for the pushrod engines was stock on the '74-'75 B20F's, and was a "smog" cam. It says it is like the D grind, but with less torque. The D grind was stock on B20's with carbs and the earlier fuel injected versions. There is also the C grind that was stock on the B18B cars. It doesn't sound like the B20 K grind is any good for performance. I'd stick with one of ipd's performance cams, and yes the VV71 is made by Isky.
