I don't think the brand matters as long as it's got plenty of teflon in it and isn't so old that it's separated.
Congrats on the guide plates, they make a difference when you get the valvetrain up to speed and harmonics get a chance to begin. Those long pushrods on the 292 flex really well, just like a guitar string under the right circumstances. Anything (reasonable) you do to prevent that or damp it out helps.
