NEW Polaris XP1000 CNC Cylinder Head - Big Port 38.8mm/33mm Valves

CryoHeat only accepts new, never-been ran Polaris XPTurbo (#3023773) or XP1000 (#3022716) cylinder heads as new core exchanges as they are virtually the same. BC uses only new XPT, XP1000 or ProXP (when applicable) for all new even exchanges. BC does not accept new RS1 heads (#3023237) due to casting inconsistencies, however the XPT or XP1000 heads are interchangeable on all big boy RZR’s. All heads come with BC bronze valve guides installed as well as +1mm Stainless Steel intake/+3.8mm Inconel exhaust valves and valve seals designed for BC's custom, threaded valve guides that will not allow the seal to "pop-off". Any valve springs, retainers, buckets, keepers, lash adjusters, cams or ARP head studs or cam cap bolt kits 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.
