From the makers of the baddest cathedral cylinder heads on the market, comes the all new Trickflow LS3 Cylinder Heads!

These heads feature fully CNC competition ported runners with a premium high-resolution surface finish for maximum airflow and performance potential. They have a 12 degree valve angle to increase piston-to-valve clearance and allow for the use of larger camshafts.
