had this head for a fair while, it was never actually used (just run it at local tuners) and i only did 100 miles on it

its got a BP (burton power?) 285 t2 cam and the heads a new built jobbie just im unsure what spec it could be as the ports are enlarged and the throats seem to have plenty of work done

any help appreciated,

it may go on ebay as i have a std lump goin in my red rst as i dont intend on using it myself
