Northwind and polar wind were coming to mind. Not sure if a Victor or BOP would work. Have a hood scoop so clearance there is not an issue

Run a Victor. Northwind is a compromise and you do not have a hood clearance issue.
Polar Wind ? I would not consider it unless the engine is huge. BOP, not sure they are even available anymore.
I have 2.20 valves on a 4.155 bore with High Ports. The longer heavier valves should not be a issue as long as you run a cam that will make power under 7000RPM and since you have a stock block I would keep it to 6500RPM or so.
You are going to need to run the right valve spring for the RPM and cam you are running. Too much spring pressure can cause problems for a stock block.
