Does anyone have experience using this head on a 1296 small journal block? It looks like it needs to be milled down to raise the compression ratio but will if flow better than a Kastner book prepped 1.38" intake valve "stock" head? I know bigger isn't always better when it comes to flow. I'm using Stahl headers and a 2 1/4" exhaust so I don't think I'm going to run into flow restriction downstream with this.
