DESCRIPTION
Speedmaster Assembled 23° Angled Cylinder Heads for Chevy Small Block 350 205cc/64cc
Features:
Speedmaster CNC ported cylinder heads are machined on dedicated 4-axis and 5-axis CNC machining centers to ensure accuracy and cost-effectiveness.
Combustion Chamber, Exhaust and Intake Ports all fully CNC machined for better flow.
CNC combustion chambers offer superior control over flame travel and quench area.
CNC Ported heads eliminate human error and variation from port to port. Unsurpassed repeatability from one cylinder head to another that is commonly found in "Hand porting & Polishing".
Combustion chambers are exact in volume - so every cylinder has the same compression ratio. Each port is the same cross section - so every cylinder can reach higher true RPM potential.
CNC machining produces ports and chambers to within tolerances of no more than 0.002"; in turn every cylinder can reach the same power potential and accurate tuning.
