Small block Chevy header gaskets forGM 604crate motors with aluminum cylinder heads.
These late model crate motor headers are for the Vortec/Fastburn S/B Chevy crate motors that are popular in most areas. Feature 1-5/8" - 1-3/4" tube diameter and 3" x 8" collectors. We list the Schoenfeld part number for easy reference.
Every NGK spark plug is designed to withstand severe mechanical and thermal shock associated with these high-revving, high-compression race crate engines.
The 602/604 DUI is designed specifically for these crate engines with two features that set it apart from regular Racing DUIs. First, the mechanical advance is calibrated on a distributor machine with an aggressive and accurate timing curve designed to meet the requirements of these crate motors. This special racing curve will ensure maximum performance and get your car out of the corners faster. Second, a melonizedgear is installed on the distributor (instead of the stock cast gear) which is compatible with factory roller cams.
