Can i use ITR Intake Valve springs for Exhaust valve springs?

Can i use ITR valve springs for Intake and Exhuast?
I want to know if this is a good idea, i don't want to reuse my old GSR intake springs onto exhuast.

The intake springs i be using is from JDM ITR 2000. 14751.P73.J02 and 14761.P73.J02
The 96 type R intake springs seem to be the same as GSR 14751.P72.003 and 14761.P72.003 anyone confirms this?
Can i use these for exhaust springs?

Anyone know what the part number of the ITR spring retainer? Not reusing old retainers.

How differnet are the valves on ITR, The exhaust valve don't seem to be different ITR part number 14721.PR3.000
looks like same as B16A.

Will i need porting to make the valves seal in the head? ITR has 3 angle i think.

My soon to be setup:
CTR cams
CTR Piston 0.25 OS
ITR Valves
ITR Rods

Any help guys much appreciated!

Yes you can use the ITR intake valve springs on the exhaust side.

But why not just use the ITR intake valve springs on the intake side and swap the GS-R intake springs over to the exhaust side. Then you would have the same setup as a stock ITR.
