The Aeroflow Series of Aluminium Cylinder Heads are taking affordable performance street and strip cylinder heads to the next level. These heads utilize ultra-smooth A356-T6 aluminium castings, new as-cast runner and chamber designs produce excellent flow numbers. This combined with a 5-angle competition valve job, diamond-honed bronze guides, hand bowl blending and professional assembly help to outperform some of the best brands in the business.

The Aeroflow Performance GM LS cylinder heads are designed for street / race performance engines to give the ultimate in flow at a competitive price. Made from A356 aluminium castings, these 11¬? LS Cathedral Port heads are designed to fit LS series engines with a small 3.90" bore. These bare 240cc heads accept 2.08" diameter intake valves and 1.60" exhaust valves and have a thicker than stock .750" deck thickness. Available in 6-bolt design to suit standard or LSX block designs.

Note: Thread sealant must be used on all rocker bolts as threads intersect with intake ports.
