Brian Crower SRT-4 +1mm Exhaust valves

BC valves are one piece design with a friction welded Stellite tip for the best possible performance. Every valve is made from premium grade, heat resistant stainless steel material to insure reliability with high boost and/or high rpm applications. The undercut stem above the head area not only reduces overall weight for extended rpm potential, but also significantly improves air/fuel flow in and out of the combustion chamber. Every valve is fully machined and features a swirl polished finish under the head.

Please specify if you are wanting triple groove (stock style) or single groove valves. Make sure you order the matching retainers with them as well if you're purchasing them too.
