Speedmaster BBC Assembled Cylinder Heads Intake Chamber

Speedmaster BBC assembled cylinder heads are complete aluminum big block Chevy cylinder heads. They are built for street and street/strip performance engine builds. Because the heads come assembled, you can skip sourcing and fitting valvetrain parts one by one, which simplifies a big block top-end build or rebuild.

Key Features:

• Assembled design: Supplied with valves and springs already installed, so the heads are ready to bolt on.
• Aluminum construction: Cast aluminum is lighter than iron and sheds heat well, which helps reduce front-end weight.
• Port and chamber options: The line is offered with a range of intake runner and combustion chamber configurations to suit different power goals.
• Camshaft-specific spring setups: Valvetrain assemblies are matched to hydraulic flat tappet, solid flat tappet, or roller camshaft styles. Choose the version that matches your cam.
• Machined valve seats and bronze guides: Seats are machined and guides are installed for reliable valve sealing and long service life.

Speedmaster is a well-known supplier of performance engine components. These heads are an affordable way to upgrade a big block Chevy. Match the head's intake runner and chamber volume, valve spring specs and camshaft type to your engine combination for the best results. Also check intake manifold and head gasket compatibility when planning your build.
