NOTES: S&S® highly recommends installing a performance cam for easier starting and better engine performance.
S&S high flow cylinder heads or CNC ported stock heads will provide further horsepower gains.
For an additional .2 bump in compression, order .030" thick head gaskets #900-0216 (2 pack). Remember to check your clearances.
These kits require tuning. When used on EFI models, S&S recommends Dynojet® Power Vision flash tuner
