    Description

    This is Fastheads economy stainless general head rebuild service.  Designed for recreational trail rider this rebuild helps eliminate premature intake valve wear, hard starting and frequent valve shim adjustments at a very low price.
    Your head
    will be returned machined, assembled and ready to bolt on.  We use high quality Kibblewhite or Ferrea stainless steel exhaust and the Pro X intake stainless valve conversion kit with heavier springs to support the 70% heavier valves, OEM exhaust springs and Viton guide seals.  Our general head service includes soda blasting to remove carbon and dirt and a full inspection. We then machine cut three angle seat profiles using our race developed Rottler SG7 seat and guide machine for perfect concentricity.  Your head is then professionally assembled and vacuum tested.  If it needs exhaust guides, most do, we will give you a call.  It adds to the package.
    We can adjust your valve shims for another , just ship your head complete with cams, lifters, rocker etc. We suggest paying after we receive your head and do the initial inspection.
    Please pay for this service after we have received and inspected your head. Mention or send a copy of this ad with your head and fill out our repair order online. THANKS in advance.
    NOTE:
    The CRF heads are originally equipped with Titanium intake valves that are 70% lighter than the steel replacements.  The extra weight of steel and heavy springs to control the extra mass reduces the power by 2 or more hp, rev a bit slower and have more of a tendency to float at high RPM's.  To retain full power or if you hit the rev limiter occasionally, race or have a modified motor we highly suggest our Ti package for 9 or our most popular Extreme Option for 9.  Our chromium nitrite PVD coated Ti valves last as long as steel and when used with Beryllium seats they outwear and are more reliable than any other system on the market.
