my dilemma, 1.6l or Pinto

OK Guys
 
Here is the dilemma you all would like to have.
 
My escort is setup with 2L brakes, sierra 5 speed.
I have a 1.6l with a ported head, unknown compression, twin webber manifold, lightened flywheel to suit. This motor is in good order only removed to paint the engine bay.
I have twin 45 webbers matched set, 38mm chokes, jetted for a 2l pinto. To fit these to the 1.6L will likely reqire rejetting.
 
Also i have a 2l, with ported head 40thou over and only 100,000ks. i have a full rebuild kit to suit this engine, with piston rings and bearings. To fit this engine will require an engineers certificate and modifiy the radiator support panel. This will require a repaint of the radiator panel, not keen on that either.
 
So im asking What would you do.
