2 be or not 2 be. Build as a 2.0 or 2.2

[beetle08]

I recently installed a fresh 2.7 in my 68L. I have the original engine, of which the block (numbers matching) and one of the cam towers is salvageable. Regrettably, the rest is fancy desk art. I am planning on rebuilding the stock motor to factory original specs, however finding 2.0 heads, pistons, and cylinders is about as easy as flying to the moon on a paper airplane. However, 2.2 parts are readily accessible. While I don't plan on building the motor immediately, I'm wondering if it's worth the expense time and effort to find the 2.0 internals, or do I build it with 2.2 internals? Opinions are welcome.

Cheers,

I would build it as a 2.2.
