i went to a local auction last week and purchase head machine just like thishttp://cgi.ebay.com/ebaymotors...ZWD1V

i did a 3 angle valve and ported n polished my head b16 and it made very noticeable difference. i have a f22a head that i am using bisimoto cams valves springs ect. bisi him self told me to use another type seat and a bigger valves. Is this machine capable of upgrading valve seats and bigger valves
