Easiest way to cap off the injector ports would be to replace injectors with 3/8" or 10mm bolts in stock injector boots. Button or socket head styles would be fairly unobtrusive. Without increasing displacement or compression, performance isn't going to change dramatically. More agressive camshafts help somewhat, as do exhaust headers. Interestingly, larger diameter valves can sometimes LOWER performance. The biggest advantage to a proper carbureted manifold is ease of maintenance. The PRV was not originally designed for the fuel injection it ultimately inherited. In carbureted form, the ignition distributor is totally exposed. Hose clamps in back of the water pump are exposed. The heater core return nipple(s -- some engines have one on each side, as does my B27F) are exposed. Of course there's nothing to tangle with the spark plug boots. My little brother timed me removing the intake manifold on my new A series engine -- 1:25 minutes, carburetor still attached. That's why I hope to some day install it in a DeLo for comparison purposes. Note that the B280 uses an intake manifold much more similar in size and shape to the original carbureted ones.
