Hi Roger, Not sure I'd want to spend 5K on an aging class 2/3 engine. When my 1.6K left one of its pistons and a chunk of the block somewhere near Goodwood, decision to move to an unported 1.8 seemed pretty simple to me (head was damaged also unfortunately). I added forged pistons too for peace of mind. A refurbed 1.8 perhaps with stronger internals would be a lot cheaper/simple, and keep the ported 1.6 head on your shelf for another day. Would also be quite valuable I think as well. Just don't buy an engine from ebay/pistonheads without proof the head isn't soft, and waste months in the garage creating a very efficient mushroom soup generator as it fails on first start, before calling in the experts to bail you out .
