In answer to your specific question - No.
However mine have all been standard and I've yet to be challenged with issues that you have - so I understand the sentiment.
Get a banger's a good call and put the zed on the back-burner for a while. Guy on .org's selling a monogram 120 for pennies and if you've got some more, another guy's got a very nice clio sport for £1500.
Saying that - got a good engine if you want one .....
