Part# CSB-VCStd-KBButn - Small Block standard valve cover Bolt Kit. This bolt kit will not rust like chrome bolts can. This KustomBitz button head bolt kit is from our standard range of 304 polished stainless steel bolts, polished to our standard Kustom Bitz finish. These are the bolts that have the Allen Key hex type slot in a shallow dome, wide flange head that looks as neat as a button on a shirt. 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 bolts, washers and spring washers to enable you to bolt a pressed tin style valve covers to a small block Chevrolet engine. The length of these bolts allows for you to use the typical 3/16 thick spreader bars that locate under the bolt heads. 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.
