This is a new after market cylinder head with Pro X stainless steel valves, heavy duty springs, keepers, Viton MX guide seals, cam caps, and exhaust studs. We also vacuum test every head before shipping to you.

For racing, full power and a more reliable package we suggest our upgraded Chromium Nitride PVD coated titanium valve package that last just as long or longer than stainless without the horsepower lose or chance of floating the valves.

The head does not come with cams, lifter buckets, or cam bearing retaining clips. You will use yours or select the complete head option.
