Use pulldowns above to build out your head.
The BC core exchange program works three ways:
1) Buy one of BC's new heads outright, no exchange.
2) Send a new head in for even exchange for one of BC's new "in-stock" heads.
3) Send a used head in, receive that same head back.
BC only accepts new, never-been ran Honda heads (#12010-HL6-A00) cylinder heads as new core exchanges. BC uses only new heads for all new even exchanges. All heads come with BC bronze valve guides installed as well as +1mm Stainless Steel intake/+1mm Inconel exhaust valves. Any valve springs, retainers, keepers or BC cams are sold separately in the pulldown menus.
If sending a new head, allow 1 week for inspection before new CNC head ships. If sending a used head, allow 4-8 weeks for that head to be ported. No exchanges on used heads. Send heads for servicing here:
