The head features a .750 raised exhaust, 20º OEM valve angle, 63cc chamber, A356 USA alloy!  We then spent extensive time wet flow testing the combustion chamber to get the exact shape needed and a better spark plug location.  We have added our solid rocker boss and revised valve location for a very stable valve train.
