Small block Trickflow heads and PRW rocker arms ???

I would think (assume) it would be the Harland Sharps as those are the ones they recommend. But, how many are running those on the TF’s? I’m reading of people using the Mancini HS versions. Has anyone compared/measured the two versions as far as final geometry goes? There are a few posts of guys using the Mancini versions on the TF’s as well as on other brands with good geometry, or what we are told is good geometry.


@lead69 is running Mancini rockers on his TF’s and they work well.
