LSA/LS3 cylinder heads
Selling a set of like new LSA cylinder heads with installed PSI 1511 springs. One head is new/never mounted and the other is from a CTS V that was driven off the lot to a race shop and then converted to a track car (bolted up but virtually new). The springs had about 15 hours of track time on them. I decided to use LS9 cylinder heads on my build instead. SOLD

LS9 heads use titanium intake valves and sodium filled exhaust. They also have larger mounting bolt holes. The castings are basically the same though.
Both LS9 and LSA heads are approx 2 lbs heavier than a LS3 head. They are both made from a rotocast process which lessons the chances of porosity.
