I drilled mine myself. i have 34 pjs i went with a 120dump 118 main and a 58 pilot. I dont have power jets or oversized bowls. i dont run more than 300ft. If i were you and you could get a deal on the 34s i get them and keep your gas carbs incase you dont like messing with the alky. I just went to it like a month ago and wont go back to gas, alky is so much cheaper and you get more power.
