ok well if they clip in and sit properly they shouldwork, the more ports is probably just the style and probably allows it to flow more fuel through. i'd recommend the throttle body because i had the stock 50 mm tb on there while i was fixing my 70mm bbk, and the day i put it on my car with the 42#ers it was completely noticable, its driveable, but its will be wanting air, and the 50mm wont be enough, it will work fine but you will feel it pull better. IMO but yea if those injectors clip in they should work, try it and if it doesnt clean em off and send em back if you can or sell them
