A popular member on Ls1tech "Denmah" put a 799 and 243 on a 5.3 and the side with the 5.3 had lwoer compression. Not by a large margin though. I personally don't think l92s are worth the effort on a stock lq4. They can't touch the 243's for throttle response and power under the curve. Now you punch out that 6.0 to a 6.1 or better and the L92's come into their own and become an epic bang for the buck feature.
My 2 cents.

Wrong. 799's and 243's are identical castings. Hardware (valves, springs) may differ but castings are the same. LS2 powered C6's and TBSS's came with 1 243 and 1 799 head.
I'll agree with your thoughts on L92/LS3 heads on a stock displacement LQ4.
Now, if you're planning on a stroker motor down the road I would definitely do it once and be done.
