Save Money on this SLP AFR Cylinder Head and Cam Package 

SLP teamed up with AFR to bring you these street/strip heads and matched them with one of their high performance LS1/LS2/LS6 cams for an even better deal. They flow enough air (up to 320 CFM intake) to work with all LS1, LS2 or LS6 small blocks as large as 427 cubic inches, down to a well-built 346. The secret to the high flow numbers is CNC porting and a newly-designed combustion chamber with a double quench pad area.
Another reason SLP picked these heads is the rugged design that can live on top of a high-power engine. Don't worry if you use nitrous or a blower because AFR's 3/4 inch-thick deck is standard, along with reinforced rocker stud bosses, thick-wall runners and interlocking ductile iron valve seats. To maximize performance, SLP includes double springs (.600 inch max lift) and titanium retainers.
To really get the full potential of these heads they matched them to their most aggressive cam for engines in the 346 CID/5.7L range.
