Info

More performance and less expensive than rebuilding used heads. No more searching junkyards looking for cylinder heads for your motor.Looks like the smog head on the outside, but has racing head features like an extra-thick deck, screw-in rocker arm studs, and raised valve cover rails.

Use 14 mm-5/8", .460 reach, taper seat spark plugs.
