Found an unknown fully worked head. Getting it tested this week.

[DarkHelmet]

The story goes, a man who raced spridgets in the 70s-80s passed on and after an estate clear out, I'm now a lucky man in possession of a, let's say, modified...head. It is thoroughly unknown. Zero documentation of the work was passed along. I made some phone calls and the people who know say the person who probably did the work isn't with us. So I am going to spend some money and discover what I have. It has valves numbered to match each cylinder, multi-angle valve jobs, back-cut as well and definitely ported. This 12g202 is quite different looking for the stock one I have. So before I put it on an engine that it doesn't deserve, I found a shop willing to flow bench it, as they built their work on cylinder head development. This is after a magnaflux tomorrow just to make sure what I have isn't scrap before I spend too much on it....So...

By all appearances, this had a LOT of time spent on it. Unused since machined and then it sat on a shelf.

Any guesses on how will it will flow? I wonder how a calverST small bore job flows....

I'll be interested to see what it does - for some good flow numbers, see if you can borrow one of Vizards bibles, I think it has some pretty good info in it.
