I am looking for some advice.
I am planning my next Fuel Injected engine, and after having tried both a centrally mounted plenum and ITBs on mt trusty old 1835cc, I am ready to move one step up the performace stage

So the engine in question is a 2110 oxyboxer, and the plan is to turbo-charge it. Therefore I will not go overboard with hugely expensive heads etc, so my plan was to use "stock" CB 044 heads, and for intake system, a German plenum and TB.
The basic idea here is to bake a "bullet proof" bottom end (hence the oxy), and cheap, off-the-shelf heads, and then "compensate" with boost when the extra power is needed. In order to keep the off-boost driveability (this will go into my daily driver '62 Ghia) I am aiming for 40x35.5 valves.
So to the question:
Will the old trusty CB end castings do the trick, or do I need to use the (newer?) so-called "high flow injection end pieces" ? The price difference is quite significant, so I am wondering if anyone could shed some light on this issue before I make up my mind.
