Not Ranked
Before you spend a bunch of money on "stuff" you may or may not need, try to decide what you are looking for - what you want to end up with and start with a plan. The important thing to remember when building and engine is to match the parts to get the required result. A bigger cam won't do you any good if your intake isn't capable of flowing the required air. Also, if your exhaust is restricting your engine, you'll hit a brick wall with hp no matter what you throw on the engine for gains.
If you are looking for around 450-500 hp, you can get there with a set of Vic. Jr. heads, a comp HR 282 or 294 cam, an Edelbrock Air Gap intake, a 393 stroker kit, your present 750 Holley, and a free flowing exhaust. And the cost would be less than the weber set up, I'm pretty sure. Very streetable, easy to build, none of the Weber tuning issues.
Your last post sounds like the tuner is just trying to get it "cleaned up" so it will run smooth with the components you have now. If the horsepower you have now is enough for you, this is probably a good plan. But, if you are looking for a good jump in horsepower, his recommendations really won't get you there.
Just my 2.5 cent's worth....
