SBC & BBC Custom built Hardcore Alum heads
All heads are purchased bare and custom assembled by us here at Hardcore, the reason we buy the bare is we can match springs accurately with your cam specs or cam we pick for you($100 off your cam if you buy heads and cam together!
On our Hardcore heads these are built with budget with quality parts in mind(Castings are made by RPC, these are NOT Pro Comp heads!), we use good quality PEP valves and springs with options to upgrade to Premium valves and Comp/Lunati springs.
