LS3 heads?
I wondered this myself...I saw a set on Ebay recently...asked the guy and he said they were 243 castings, but didn't know the chamber cc or valve sizes.
If they are 243's are they using this casting and changing the intake bolt pattern?

exactly, but just because its made for soemthing else doenst mean it wont work, and work well it does. You just need the right intake with the right rockers (exhaust i believe) and if you keep the L76 injectors you have to get an adaptor harness from speartech to you those "newer" style injector with your "older" style LS1 injector harness. The "newer" LS2 and up injectors are shorter and have a different plug as well. Hope this helps
