My friend here (Karoo, South Africa) runs a small machine work-shop. He's got a 1976 Isuzu Bellet 1500 sport sedan - with twin side-drafts. It's the only one in South Africa - a classic, they say it will do 120 mph - pretty fast for an 'old' 1500 motor. Problem is, the head gasket has gone, and the head has been skimmed too many times already. He wants to make up an aluminium plate to restore it, but needs to know the stock head thickness. If anyone knows anything about Isuzu Bellets, or where I can find info - I'd be very grateful
update: just found out it's a G161Z motor..
