don't think it would be much of a problem to have the bits made up

i had a set of billet cams and valves ,buckets made for my rovert16
had lot more lift on the cams i had to machine the head for bigger diameter buckets
so it can be done

it not that pitted a skim on the head face and the buckets diameter are clean
combustion chambers can be cleaned up ect

any one got any idea what it could be worth

thanks for the info so far
