32 Valve Stag!

I have always harboured a desire to build a 32 valve Stag motor, it just needs to be done! To that end I have a couple of Stag V8's sitting in the engine shop awaiting the glorious day.They are placed in such a manner so that I catch my shin on them every now and again to remind me why they are there!
It's not an idle dream either, I know it existed as a paperwork exercise in Triumph experimental early on in the seventies, but did it progress further? A school mate of mine's Dad ran a small engineering shop locally specialising in amongst other things construction of race winning motorcycle combination outfits, but what he was really known for throughout the Midlands was his ace ability in the black art of aluminium welding. At least it was in those days, I remember his tig plant being virtually the size of the end wall of his industrial unit, nowadays they are much more manageable. Anyway as I recall said mate and I popped into his Dad's unit on the way home from school one day in the mid seventies to check out the latest motorcycle combi, only to be confronted with his Dad 'doing a late one' for some lucrative hush hush British Leyland contract. Obviously oblivious to my even then unatural interest in all things Triumph he didn't make any attempt to cover up what he was doing. Mounted on a comprehensive alighnment jig was what looked like a Sprint head with a Stag chain box being carefully welded on the wrong end? I remember asking my Dad at the time if he knew anything about it (Dad worked near to experimental at Triumph and in the course of his job regularly found excuse to have a nose, and take the odd picture in there!) only to be met with a blank expression? So is that as far as it got? I must remember to ask my mate Pete Clarke (former experimental), he was one of the team on the mini 'production line' building the Stag engine saloons/estates in experimental, maybe he might recall how far things progressed?
