What all is needed for the ls3 heads to be installed on an lq9 on a 00 ta? Sorry if you have posted.
I need a price for a set of ls3 heads with the hollow valves with whatever I need as well as a price of an ls3 intake with injectors and rails.
Will my center bold valve covers work with the ls3 heads? Sorry so many questions.. spun a bearing and picked up an lq9 so it was kinda quick.

Very interested in a set of rectangle ports.
I know that LSA heads are off the supercharged engines and are very similar to the L92/LS3 heads, but can you or anyone else tell me the specific differences between them? I tried searching.

GM says:
"The LSA heads feature a unique "wing'' cast into each intake port to promote a swirling motion that blends the pressurized air-fuel charge. The heads are also cast from a premium A356-T6 alloy, which better manages the heat generated in a supercharged engine. A356-T6 pays particular dividends in the thin bridge area between the intake and exhaust valves, where effective heat dissipation is crucial to both performance and long-term durability. Finally, the LSA heads are rotacast. This process rotates the head mold as the molten alloy cools and essentially eliminates porosity, or microscopic pockets of air trapped in the casting. Rotacasting delivers a stronger part that helps maintain performance and structural integrity over the life of the engine.(The heads are nearly identical between the LS9 and LSA)
Valves are among the most heat-stressed parts in an engine, and their wear resistance is crucial to long-term durability. Those in the LSA are manufactured from a high-chromium steel alloy called SilChrome 1 (The only difference between the LSA's exhaust valves, and the LS9s is that the LS9's are filled with sodium for the extra heat protection -- the LS9s intake valves are made of titanium.), with thicker heads than most other Gen IV V-8s. They promote heat transfer away from the valve face and valve guide to the cooler end of the stem, where it more readily dissipates. This maintains a lower, more uniform valve temperature, reducing wear on the valve guide for better alignment and a consistent seal between the valve seat and valve face over the life of the engine. The intake valves measure 55 mm in diameter and the exhaust valves, 44 mm.
