Hi mate, i have a couple of heads for sale, 1 8 port and the other 4 port, one has been sat outside for ages with the cam covers off under a tarpaulin so might be junk but i'll sell the whole engine cheap if you want it ? the 4 port is disassembled so might not be of much use
if u can make it to my town mate u can have a stock head for free i got abot 15 laying arround i will charge for ported head stock u can have for free
