What was your criteria for heads that lead you to the 243 heads. As I said in the other thread, if you werent specifically looking for 243 heads from an LS6 to get the sodium filled valves and different valve springs, then I would think 799 heads were easier to come by and probably cheaper.
Reason I ask, I have been contemplating (not that it would happen anytime soon) an LS budget build for the Z06 instead of molesting the LS6. I would think you could find an iron block and some cheaper heads that would more than make up for the extra weight.

The Vortec 5300 L33 (VIN code "B") is an aluminum block version of the LM7, and was referred to as the Vortec 5300 HO in marketing materials. However it should be noted that the L33 uses a flat top piston from the 4.8L instead of the standard dish piston found in the LM7. It also uses 799 cylinder heads, which are identical to the 243 casting found on the LS6 and LS2 with the exception to the Corvette spec valve springs, and hollow stem exhaust valves on the 2002-2004 LS6. This combination increased the compression from 9.5:1 to 10.0:1. Also the L33 had a specific camshaft not shared with any other engine, with lobe lift of 7.2 mm, 193 degrees of intake and exhaust duration, and a 116 degree lobe separation angle. As a result power increased by 15 hp (11 kW), to 310 hp (230 kW) and 335 lbft (441 Nm). It was only available on extended cab 4WD pickup trucks. Only 25% of trucks made in 2005 had the L33 engine.
