torque plate honing small block

[femtnmax]

All torque plates in our area are for cast iron heads.  I will be running aluminum heads, so bore distortion using cast iron plates won't be correct.
Should I:
go ahead and use torque plates for cast iron, and accept that bores won't be truly round.
OR
Don't use torque plate at all, and accept that bores won't be truly round.

Second issue:
the block I have was bored and honed without torque plates.  I am guessing that to finish hone with torque plates could increase the cylinder diameter about 0.001-0.0015, which would put my piston cylinder wall clearance for wiseco forged pistons at a maximum clearance between 0.005-0.0055.  Should I find another block, OR should I just run the bore/hone job that is there and try my best to get the rings to seat.
any comments??

Who says you must use an "Aluminum" Torque Plate, for Aluminum Head applications ?

Assuming your Block Decks and Torque Plate are both Flat, all you are simulating is bore distortion caused by the Fasteners(Bolts or Studs), and Clampload.

I highly doubt an Aluminum Plate, will distort differently than a Cast Plate ?

Do you have a reference that says this must be done ?

I agree with Bob....a steel plate will work fine for honing purposes.
