I had a run where I was building engines for street rod guys when stationed in Vegas, they loved those stainless ribbed hoses, I hated them... LOL
Stock hoses are where it's at in my book. Sounds like you are going to be close with the carb, fire it, warm it up, get it to idle and set timing (may as well go 14-16 initial, that's about where you will be with the new distributor so you'll know what it feels like at idle anyway), then fine tune idle a/f (should be pretty close as is)
In the event the new distributor makes it feel a little less responsive, don't sweat it, your advance is too quick now, which may feel good, but when you don't have to worry about ping/rattle anymore, your engine will thank you
