seems to be some confusion here. What was auctioned was an early LZ14 head from around 1973, PB110 era, there's less than ten operational world wide. It was a bare head, and the price was kinda reasonable, but to recommission it would cost lots, no valves valve springs cams and more importantly cam buckets. The green LZ20B is a type 2 rally head probably PA10 or S10, there's a few of these around at least four running engines in Australia, 1 x LZ20B, 1 x LZ18 and LZ14 rally engines and one turboed LZ20B track engine.

There is currently an LZ20B head and turbo on yahoo auctions, it's a bare head and would cost around $30k on top of the purchase price to make it work.

The cams from the type 1 and type 2 heads are not interchangeable

good info thanks

Very interesting thread, I learnt a few things today.

another early LZ head at auction. Did not sell at 450,000 yen (4,600 aud or 3,000 usd)

Might be the same head as sold a year ago last January for 485,000

I don't know if those are new yet-to-be-used valve seats installed, but i'm surprised it looks to be just a one-angle type and not blended into the ports very well. Even a stock A12 has three-angle valve seats

The beauty of these head are not that they are just twin-cam, but more that they are 16-valve heads. A junkyard KA24DE would be more powerful perhaps, but this is period cool
