Part# CSB-VCStdSpcr-KBDome - Small Block standard valve cover Bolt Kit when using our AussieSpeed 12mm [3/4 inch] spacers for roller rocker clearance. This bolt kit will not rust like chrome bolts can. This KustomBitz dome nuts and studs bolt kit is from our standard range of polished stainless steel bolts, polished to our standard Kustom Bitz finish. This custom valve cover, rocker covers, tappet covers, bolt kit will suit all early 4 bolt style small block Chev 307, 327, 350, 400 V8 engines. This bolt kit comes complete with 8 x dome nuts, grade 8 studs with hex slot, washers and spring washers to enable you to bolt a pressed tin style valve covers and one of our AussieSpeed 12mm valve cover spacers and two corke style gaskets to a small block Chevrolet engine. The length of these studs also allows for you to use the typical 3/16 thick spreader bars that locate under the bolt heads or in this case under the dome nut and washers. This kit is also suited to the Mickey Thompson style diecast Alloy rocker covers that have a 3/16 to 1/4 inch thick flange when used with no spreader bars.  AussieSpeed rocker cover spacers are so easy to fit when using a Kustom Bitz Stud kit.
