Carbs or Injection?

[volvo164]

One more technical question.

Are there any sensors or any other part of the Fuel Injection System that it should be attached to the engine block and not the Cylinder Head?
I am asking because my engine is a B30A.

After going through several posts and your comments I think I am going to take one step at a time.
First I am going to replace the cylinder head with the B30E after having it converted for unleaded and keep the carbs.
Then I will either try and find new parts for the D-Jet or use parts of a newer model or megasquirt.
I am after originality but:
- By using newer parts is it going to make a big difference in fuel consumption?
- From the visual aspect will someone be able to tell that the parts are newer than the car?

Does anyone know if there are any sensors or any other part of the D-Jet that it should be attached to the engine block and not the Cylinder Head?
I am asking because my block is a B30A.

And finally:

If I replace my stock B30A cylinder head with the B30E and keep the carbs on is there going to be an improvement in performance due to the higher compression?
Are there any other differences between A and E besides the higher compression ratio? I mean does it also have bigger valves or lower profile camshaft?

Do I need to make any changes to the carbs as well? (i.e. Needles)

Thank you!

I think you will have problems with a B30E higher compression head on carbs , Fuel injection is better able to control "pinking" due it's precise nature and each injectior delivering exactly the same amount of fuel . With the carbs , 3 cylinders drawing on one carb there is bound to be variation in fuel mixture strengths on those 3 cylinders , some weak some richer so the weaker ones will " pink " .. I remember way back the standard B20B sensitive to the new unleaded fuel when it came out and prone to pinking and running on ..
