If i were you i'd buy a '6 lump and take a few months to rebuild it with port and polished bits and 3 angle valve seats etcetc then drop that in. 306's are so easy to change engines on and you could probably pick one up dirt cheap as a tapper or rings gone or cambelt snapped or whatever.
Doesnt even own a 306.
