As far as how many dyno pulls and test sessions I've have been involved with on legal SB Mopar V8 NHRA stocker motors it is over hundred so far, how about you?
Same number as you've done with the big port intake on the small port heads, which was the question asked.
This isn't the race forum where you turd polish an engine to rules complying perfection and if you had issues with the big port intake on the small port heads my experiences running them ON THE STREET doesn't match yours. It has always been an improvement over the 2bbl setup. Which is exactly what the OP is asking about.
As an aside, Edelbrock still makes a 4bbl intake with small ports, it's called the Performer and running one of those on my 318 is exactly the same as running a stock 4bbl intake on small port 318. BTDT.
