Proform Rollers

Be careful with the 273 rockers though...that's what I originally put on my car. I DID'T use the old type banana cut rocker shafts (didn't know they existed), and even after I polished the surfaces, the used rockers ate into my rocker shaft after a few hundred miles, hence why I went to the rollers...oh well...it was a good excuse to get Chrome rocker shafts.
