The Project Pad

So I've been running a "Eurospec" 2.6L shortdeck (and probably short rod) 2.6L for several years with a tweeked/ported/big valve 20v head and a 276deg. Schrick, 034 eFI e85 blah, blah....

See here for more info: http://www.theprojectpad.com/viewtopic.php?f=10&t=1738

I've verified that it's definitely a shortdeck, but not a 2.3L block, someone suggested it came from South Africa? "Audi-engine AAY, 2480 ccm, 100 kw Petrol only made in SA": http://www.s2forum.com/forum/showthread.php?t=72559

It has brutal midrange torque, but runs out of breath at 5,750. It's in a 2300lb fwd. car that I rarely drive on the street, mostly track (as you probably figured from the pics).
Anyways, I wanna put a 20V head on it, I know that means I'll have to change the pistons.
Also, before anybody says anything: NO TURBO!!
More importantly, what kind of work should I do to the head? If I dropped it off at big Hanks shop and got the CNC porting done... what else?
I know that having a long stroke engine with a ton of rod angle affects tuning, I figured the 20v will let that bottom end breathe way it wants to!

google can translate it if you dont speak german

For the future 20v head!

Just (over the last year) built the same engine - yes, they are SA blocks that were put in the Vanagons there.

Yes, you are correct that they are "short block", but taller than the 7A etc. blocks.

I came to the conclusion, after many iterations, that I had go go full AAN accessories with that block - IF you want to use the AAN intake.

I't running, on VEMS, but I'm chasing a bad sound....

Any idea what the rod length is? Are the pistons/pin height compatible with any VW pistons? (I want to run flat top pistons so i can run a 20v head)....
