Preferred carburetor for mild 360?

Thanks for all the help here, guys... I really appreciate it. it's all a little overwhelming to me, ... I know cameras, photography, and can talk f-stops, lighting ratios, color balance and bit depth all day long... when it comes to something like tuning an engine like this - I guess I'm lost. I'll put the plugs back in and see where the initial timing and total timing are currently at, and then I'll check the metering rods at idle to ensure they're in the 'down' position once I get the timing set. I wish I could hire one of you guys to come over and help me nail this all down!
