Fiesta camshaft over

Hi, the camshaft of my Fiestas 1.3, year 11/96, says goodbye (just 100,000 km!). At Ford the problem is known, but they only offer bulwark up to four years! Now I am thinking about whether I should not have a “better” camshaft installed, but do not know if this is profitable, both performance and price-related. Since I am a bloody layman, I also do not know what possibilities or differences there may be. g and tell me about it? Would be great! Pebbles
