It's all in your head

Just acquired a Star racing cylinder head for the bike, it's been fairly heavily modified- with 31mm inlet & 26mm exhaust valves which are titanium, as are the retainers. Some fairly huge ports compared to my head and epoxied floors to reshape them. Seems to be in pretty good shape, it's supposed to be an older style prostock head. It's unlikely it's been used for nitrous anyway as there are no holes for the floggers.
It should provide a fair amount of extra HP, not sure if i need it just yet but it's come along at good price and it'd be silly to let it pass by.
