[Fot] Triumph Spitfire big valve head questions

[Mike Harmuth]

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.
