hi, i'm about to rebuild my 1.4sr engine and am considering fitting a 32/34dtml carb to it but need to know what is involved? and is it worth it?

during rebuild i'm gonna skim the head to raise compression slightly, clean and relap in the valves, fit new valve stem oil seals, hopefully camshaft and poss vernier, uprated valve springs if i fit an uprated camshaft. match up the exhaust ports and give all the ports a good clean. uprated zorst manifold.(already got a full magnex). then in the block just gonna change the bearing caps.

does it all sound worth it? and can i expect good results?
cheers chris
