you can use the escort one pal, have to be diy, as long as youve got the gaskets, inlet manifold youl be ok, do you know what car they came off? Bogg bros up north will sort the tune out for £80 on the rollers, the carbs are very simple to fit though, ideally youl need a different maniold and a decent exhaust and cam to make the most of them though
