Dart Machinery, which celebrated its 40th Anniversary in 2021, has introduced a redesigned and improved SHP Series cylinder head for small block Chevrolet muscle car and street rod applications.
Based on the popular 23° valve angle configuration, it features revised port designs to deliver significant power improvements at budget-friendly affordability. Manufactured using a proprietary process employing permanent molds and a dense aluminum alloy, the intake and exhaust runners, plus the combustion chamber, are exceptionally smooth as-cast. This provides excellent power gains at optimum cost efficiency.
The SHP Series heads are available from Dart in bare form or completely assembled. Bare heads come with powder metal seats, multi-angle valve jobs, magnesium- bronze valve guides and .530” seals. Assembled heads include Manley stainless steel intake and exhaust valves (7° or 10° retainers), choice of 1.250”, 1.437” or 1.550” valve springs to compliment the camshaft design, Viton valve seals, hardened spring cups, a Dart two-piece guide plate and ARP rocker arm studs.
