What about just welding up the holes in the case and drilling new ones to fit the heads you use? Or even welding the heads and holes to fit the case?
You might have to build a jig, or just be good in layout.

yep, I want heavy everything. Nothing builds that 500 RPM grunt, low down pulling power more than a heavy rotating, and reciprocating mass. This one is not good for more than 5500RPM, I'm more interested in power below 3500RPM.I want a 3000 RPM torque peak with this monster. All this, and with the CIS it should be interesting to see what happens.
I have contemplated running 029 bus pistons with a 15cc dish Vs the 914 pistons as that way I can run even a tighter deck and smaller chamber and let the dish drop the CR where I want it. This would still be done ina 94mm TI cylinder, with increased skirt clearance and a chrome top ring, iron second ring and 5 piece Goetze oil ring with decreased tension for better lubing. That along with a 12,5 and 7 o clock rod mod that I normally use on TIV engines should keep teh cylinders nice and wet, even at low revs, with less crankshaft centrifugal force to feed the bearings. I plan on using a wet sump autocraft pump to supply enough pressure to keep the entire engine wet at revs below 750RPM with atleast a 50% load on the engine.

Sounds like you want to go rock crawling with some Jeep guys in the mountains 
I have been looking at the 025 pistons pretty close, but that would be a heck of a cut in the heads to get any compression since the 025 pistons are dished so much. Not that I am looking for huge compression, but the dish is huge. Seems much easier to me just to stick with the T1 94Bs as they are semi-forged and lighter.
