try some of these peeps who advertise brand new heads .....

woodford motorsport on www.cosworth.info or 01803 863958 they advertise it brand new and i hope u are sitting down.... at £1450

also try www.burtonpower.co.uk 020 8554 2281 they are a brilliant company just like woodfords above !!!

think if the companys supply new heads then im sure they will all be very close to same prices buddy !!

good luck
