SLP / AFR Cylinder Head & Cam Package, 1999-05 402 CID LS/LS2 600 HP
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. 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, 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" 250º
ex: .596" 246º
Centerline - 114º
Lobe Separation - 114º
Best of all, you’ll 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.

It won't fit. Your heads are perimeter bolt design not center bolt. That H/C package is put together by SLP not Imperformance. As stated above check out some of the sponsors. My H/C package costs considerably less and made more hp than their's. JMHO!
Texas-Speed has a PRC Stage 1 heads/Cam for 1800 i believe... they even have a gasket kit with everything you'll need. Check some of the threads on the board, 224/224 is just about the standard these days, and it just wilder as you go bigger...
