Any good engineering shops that can convert the head to run on UL without additives on my L28e engine that anyone can recommend? Need to find a good price and someone who knows what they are doing when putting in new guides and exhaust seats and may have access to new exhaust valves.
Thanks in advance.
 
L28E engine should already be compatible with unleaded. In the UK all L-series engines were officially designated by Nissan as unleaded compatible from 1978 - so late 260Z and all 280ZX.
In USA unleaded compatibility would have been mandatory from about 1974.
