    1.3 HK Engine Mods

    1 point
    I’d just like to resurrect this thread for a moment as i can’t find a definitive answer elsewhere. Will a mechanical HK 1.3 head go onto a 3F GT block? Do both mainfolds match up? Does the GT dizzy fit properly? Does the stat housing need changing? I gather that the HK head was a favoured one for cam and valve upgrades, preferable to the GT hydraulic head.
