Valves listed below are 0.100" longer from the head to the keeper grooves. Provide more install clearance for more spring installed height. Note 1: We do not use or sell single keeper groove valves as we have never had a wear problem when Berg GB 344 keepers or when other keepers are properly modified as stated in GB 801-HEADS. Furthermore, the Chevy type single groove keeper requires a special (non standard VW) angled retainer to match that keeper. Note 2: Other head sizes and lengths can be special ordered. Minimum of 8 per size must be ordered and paid in full before production is started. Once work is started they cannot be canceled. Allow up to 8 weeks delivery. Price is the same as listed for above valves. Note 3: Valve head size can be cut down to what you require should we not have exactly the size you need. See LA VALVE010-4. |
