Since you are asking questions about correct install of engine items...couldn't help but notice your throttle spring placement. The factory install would have been completely different...also I see a vacuum hose connected to a port near the air-horn on the carburetor...can't quite see where it goes, but it looks like it is running to the distributor vacuum advance ?? If so, this will not give you the correct vacuum source for the advance.
Not sure what level of 'correctness' you are after...but, we can post some photos as a reference if you want.
How about posting a few photos of your car...we love pictures
