first of all, a 1g (6-bolt) intake manifold wont fit onto a 2g head. the bolt holes do not line up.

second, as far as the throttle body, it would fit. BUT the hole is bigger than the opening of a 2g intake manifold, which would result in the air bottle-necking.

what you COULD do is put a 1g head on your stock 2g block, and therefore use the 1g intake mani and tb. plus, the 1g head flows a lot better than a 2g head.
