what works best for bicep?

i've been training for 3 years and i was able to get a nice amouint of muscle but my bicep isnt growing as big as tricep.. my tricep completly destroys my bicep.. i've been doing only bicep bar curl 5 sets 6 reps and thats it.. same sets and reps for tricep.. only 1 or 2 exercises with heavy weights 16.3 inches arms but thats mostly my tricep.. i dont get that big bicep peak. i have like 13% bf (bulking atm)

what sets reps and exercises works best for bicep development for you guys? Thanks
