It looks like something we would all want. I didn’t see a price for it.
I'm curious about where a thermostat is mounted (or how that issue is resolved)? Also, does the Vizza have its own specific valve cover, or does it use a stock 850 cover? Seeing as how 2 of the 4 valve cover mounting studs are on top of the (edge of the) intake manifold, how is the resulting gap between the valve cover bottom & the head surface dealt with?Does anyone have experience with Vizza's 8-port head? I've been looking at them for a while for my 903 and am curious about how they perform.
Good questions and observations.I'm curious about where a thermostat is mounted (or how that issue is resolved)?

The "other heads" with the water exit are PBS late style heads offered in Europe. PBS has an agreement with Michael Feyl of Scuderina Topolino to market/produce them. The 8-port head I show has the water exit out the flywheel side of the head via the allen head plug area found in all 850 heads. The early type PBS head had the water exit above the front pulley end of the head. Jeff Stich has been marketing one of these outlets on Ebay and this forum. It's easy to use a free standing thermostat for temperature regulating purposes. Certain 124 Fiats have these and are available for around $20. The amount of external plumbing is a little hard to make look neat though. I hope I don't offend anyone by getting so far off track as to not limit my conversation to only the exact model in discussion. I thought that once the conversation was opened to "other 8-port heads" it might be within parameters....Good questions and observations.
The other heads like this had the coolant exit between the two pairs on the intake manifold as I recall. The whole how to hold a valve cover question does look like a fussy problem to resolve.
No,Is yours a Vizza 8-port head, as well? (The intake mounting looks different between the Vizza 8P shown by the OP).
Nice job of sleuthing that out!.I had a discussion on Facebook with a gentleman from Argentina who claims to own one of these heads. I says he's very happy with it. Regarding the thermostat and mount, the coolant exits in the rear of the head (toward the firewall, see below). It doesn't need a special valve cover. To mount the cover, the guy said he created an 'S' piece out of aluminum to hold the intake side down.
Apparently the guy who makes them is Giuseppe La Russa and is a member of Facebook and lives in Trapani, Italy. The owner purchased the head directly from Giuseppe, not through Vizza.
