2270 Deck Height and CR, Pistons sitting proud of the deck, how many shims is too many shims? Options

Hey folks! I have the bottom-end of my 2270 assembled and spinning freely. Thanks to all who helped me get to this point!

To quickly recap: I bought the 2257 kit from AA Pistons (78mm stroke, 5.158" rods, etc.). And when I threw a P&C on for a test-fit last weekend, I immediately noticed the piston sitting proud of the deck height at TDC (negative deck) by about 2mm.

Before I overreact, or buy the wrong stuff, I thought I'd ping the community...

1. Is this normal for a stroker set-up?
2. Can you stack multiple shims when getting up into the .06 >> .09 range?
3. (If no-stack) What's the best place to have custom shims cut?
4. I recall Jake saying using large shims requires lots of advance, anyone have experience here? What am I looking to adjust for upon start-up?

Once I figure out whether or not this is normal (I.E. verifying that I don't have to backtrack), I'll get into the CR questions (just waiting on clear plastic from Amazon so that I can measure my CC volume this weekend) (IMG:style_emoticons/default/biggrin.gif)

Thanks!

I lied somewhere. I said my chamber volume was 54cc. It is 52cc. My base cylinder shim is .140 in. I don't use a head gasket. My rods are 5.325 (vw length). I run big valve 44x38 1.8 heads with 2.0 angle 12mm plugs by Headflow Masters. Adrian was the go to guy in 2002.

Why did I take it apart. I have Dirk Wright disease. I took it out to bench run it and look for a tiny oil leak. I still had good compression and leak down above 96%. I replaced my Shadek oil pump because it was at max undersize. I installed a non stock oil pressure relief valve. The part stuck in the bore & I was running without gauges. I took it apart and found the oil pressure relief valve scored. So I decided to replace all of the bearings and rings and cylinders
