I didn't realise Guy that you were into Jaguar XK 6 cylinder engines. It would be great if i could persuade my father to modify his old E-Type engine.
Those pistons look pretty amazing compared to the standard pistons. That is going to have quite a bit of compression increase. Is this head prep for race or road car use?

Just about a classic hemi head. Do you have any feelings or thoughts about twin-plugging them?
