hey, would a 7A head fit a 2.5 liter AAF euro-van(1993)? and would the AAF block bolt into a 90Q20V?
just wondering...
thanks

Yes, it would.

Yes, it would.

But.....The compression ratio would be too low, the AAF code motor only has 8.5:1 CR, so bolting any 20v head onto it would result in an even lower CR, making it have poor emissions as well as very poor off-boost performance (ie, lotsa lag).

what about milling the head a little to increase Compression?

It'd have to be a LOT. You are only talking about somewhere around 7:1 CR resulting from the two.
