QualCast has announced its new QualFast CNC Series ported cylinder head product line. CNC-machined in the USA, these aluminum heads unlock higher performance with superior quality. The new QualFast CNC Series heads are available in Small Block Chevy, LS1, LS3 and LS7 castings with bronze guides and valve seats installed, as well as in highly popular and affordable cylinder head kits.

The CNC Series SBC kits include two CNC heads, various combinations of street or Black Lightning performance valves, performance valve springs, spring inserts, retainers, keepers, stem seals, rocker studs, and guides plates for one engine. LS series kits come without rocker studs or guide plates. The QualFast catalog offers additional roller rocker sets with poly locks for SBC.

QualCast also offers BBC, SBF, and BBF unported aluminum heads and cylinder head kits. When you need speed, turn to the new QualFast CNC Series heads with ported combustion chambers, intake, and exhaust runners. Flow numbers provided by the Saenz digital AD-680 Flow bench result in 15-25% greater flow compared to the unported heads.
