20vt head v. 10vt head

[Stephen Williams <mannlaw@indy.net>]

	Couple of questions, one that may be stupid.

	1.  Will the 20vt head bolt on to a pre-91 Audi turbo motor?

	2.  Anyone have the cc's handy for the 20vt head and the 89 dual
knock turbo head?  In other words, how do they compare?

	Thanks,

	Bruce
