But you can contact sellers via PM, right? I think there are at least three sets for sale last I checked.

Be aware that there are small differences between the 5364 casting and 823/821 casting. 5364 has a bit more meat

It is my understanding the ls3/l92 heads are basically the same casting (l92 truck version has heavier valves). The LSA/ls9 heads have the thicker decks and are also rotocast to lower porosity (make the casting denser). They also have "wings/fins" to improve low rpm burn/emissions... But when ported these get removed. The 5364 casting is from a vette or G8 I believe. Head casting info towards bottom: http://www.chevyhardcore.com/tech-st...ags-to-riches/

What kind of port development? I have a set of good ones. But I need them for a motor in putting together. How long is it going to take? I will need them back

... well I'm looking to do different levels, Stage1/Stage2 ... afterwards I'll be drilling holes in the ports to make sure there's enough material left ...

... it needs to be damaged 1st, cause it certainly will be afterwards lol ...
