Save Money on this SLP AFR Cylinder Head and Cam Package

We teamed up with AFR to bring you these street/strip heads and matched them with one of our high performance LS1/LS2/LS6 cams for an even better deal. The heads flow enough air (up to 320 CFM intake) to keep up with our ZL402 engines but they work with all LS1, LS2 or LS6 small blocks as large as 427 cubic inches. The secret to the high flow numbers are CNC porting and a newly designed combustion chamber with a double quench pad area.
Another reason we picked these heads is the rugged design that can live on top of a high-power engine. Dont worry if you use nitrous or a blower because AFRs 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, we include double springs (.600 inch max lift) and titanium retainers.
To really get the full potential of these heads we matched them to our most aggressive cam for larger displacement engines.
Camshaft Specs: Valve Lift Duration@.050
in: .596 inch 250 degree
ex: .596 inch 246 degree

Centerline - 114 degree
Lobe Separation - 114 degree

Best of all, you will save $25 over the cost of purchasing the parts separately!

NOTES: These heads are ready to bolt on, but we recommend that final assembly of any engine be performed by an experienced, professional mechanic.
