I had thought of using 205 pistons + head on the 185 block - but still utilising the 185 inlet manifold ..

Won't work.. the ports are different. The ST205 doesn't have TVIS. The ST205 pistons are no different to the ST185 models from memory.

Ive just found out the exhaust manifolds are different - So this is a X against using the 205 block

Its not a "X" against the 205 block, cause the exhaust manifold bolts to the head, not the block. They are only slightly different. The ST185 manifold is prone to warping slightly at high temps.. the ST205 has an extra (or 2?) studs to stop this happening.

would a 185 block with 205 type internals happily handlye upwards to 350 horsies without the need for forgies - and would the head flow as well or in near as figures to the oval type setup on the 205

A ST185 block with ST205 pistons won't handle any more power than a ST185 block with ST185 pistons, in my opinion.
I think the main benefits of the ST205 is its intake, turbo, intercooler and ECU (ie. no AFM etc). However, if you are high flowing the turbo, changing the intercooler and maybe running an Autronic, then I can't see why starting with a 205 engine would have any advantages??
