I am about to start building my 250, 1.6 rockers, bigger cam kit, header, etc. I want to pull the head and porth the exhaust valves a little bit and clean up the bowls, maybe a 3 angle valve job. I have read about the 2v conversion and it would be expensive for me to have someone do it and I dont have the tools to do it myself but I want more air and fuel into the engine. I was wondering if anyone has tried to just bore out the hole for the single barrel a bit, and then matched that bore on the adapter Instead of doing the whole mill fill mill so the adapter could still be bolted on but also give a bigger hole for the extra air/fuel
