Clifford Research used to be the popular source, but I've not heard much about them of late. I did look on the web and they still have an online store.
I knew a guy years ago who drag raced a slant six. My gosh he was possessed with that engine. Spent a fortune on it. After the first handful of performance improvement add on stuff, weak links in the engine started showing up, and that's when it really go expensive.
Lead, follow or get the hell out of the way

The slant and the Australian engine have no parts in common. None of the heads are any good. There has been a discussion of an aluminum head for 30 years, and nothing done. No, the Jaguar, Toyota, blah heads do not fit.

What do you need John? First thing you need to do with a Slant is make a reasonable plan of what you want it to do. With a little motor it is way easy to get off track and have a real turd. The key to a Slant is getting a good head on it. When you start with postage stamp size ports and nickel and dime sized valves it's hard to make power. The best Slant head porter in the country has retired now, but I know where all his stuff went. Torqstorm is making a reasonably priced bolt-on blower kit now. It makes 8 or 9 psi which should wake up a fairly stock motor very well. Boost is where it's at if you want to go fast. Avoid Clifford like a plague. The clown running it now doesn't know his butt from a hole in the ground. Clifford used to make really good stuff, especially intakes and headers. Those pop up used all the time, and it is much easier than dealing with Clifford direct. Be patient and watch the for sale pages, E-bay and even Craigslist. Guys get tired and dump their new/used stuff all the time. The Achilles Heel of the Slant is the oil pump drive gear. We went through a few years of people having the gear fail and lose motors. I had one do it. Not sure if it was ever solved, but it seemed to be more common when using Mopar Performance cams. Very seldom will you have a bottom end issue. You will hear that it's only a 4 main block, but you will never see a web crack like a big block even at 600+ horse. www.slantsix.org is a wealth of information if you know who to listen to. There are a couple knotheads on there that will reply to every question without having a clue what they are talking about.

There has been a discussion of an aluminum head for 30 years, and nothing done. You are very wrong there. Many attempts have been made to get an aluminum head made. The issue is the market is so small nobody can agree on what they really want. I have been involved in 3 deals myself. 2 died because we could not get 6 people to agree on how the head should be done. 1 died because the main investor suffered a personal tragedy. The Aussies cast alloy heads for almost anything and won't do one. That alone should tell you there is no market. There were 7 factory aluminum heads made. Some still exist. There was no advantage to just making the head alloy. Howard Davis had his own billet head made. Not sure how much money he spent on it, but he did it his way.

By "attempts" you mean "we talked about it, but no physical product was cast". "Done" means "here is the head, it may still need some work". It wasn't done. The discussion you referred to is the same as every aftermarket head: the more improvements (raised ports, bigger ports, relocated intake valve, valve stem angle changed, rocker shaft moved, chamber shape change, spark plug moved), the more expensive (and slow to develop) it becomes, fewer people want it, and the more special parts it needs. As you said, just making it alloy not only does almost nothing (except save weight) for power (which many, many owners do not understand), but wayyy too expensive for a nearly stock 200 hp engine. A cure for the pump drive with pictures can be found on the slant site - it involves tapping pressure to squirt the gears. The Torqstorm looks good, won't need any other mods except header.

There was no advantage to just making the head alloy. Howard Davis had his own billet head made. Not sure how much money he spent on it, but he did it his way. Considering the slant has had a long reputable production run in the millions across the globe, its a reliable engine, very well known, and yet the market can find the rational for building alum heads for 409's,. Ford Y blocks, AMC's, etc Other then marked red comment above, which is a huge hurdle, I don't see a market UNTIL an alum head is offered. Chicken or the egg scenario. Since the slants are still plentiful and still affordable, and its likely a turbo build will get at least equal attention as a stock Hemi at a car show. The alloy advantage is always weight. No matter what, the client base is dying off. Slant's 12,500,000 over 22 years 409's 1965 2,828 car production ceased 1964 10,625 1963 21,267 1962 8,909 1861 142

One thing you have to remember, 99% of Slant owners are cheap bastards that cry about a $12 set of plugs. Many cry that they want an aluminum head, but most doing the crying want it ready to bolt on for $350. I've been involved in enough attempts to know. You want one? Do like Howard did and dig in your pocket and do it yourself. Then there is no arguing.
The biggest limiting factor is the tiny bore size. A big port head is not much use when you have the cylinder shrouding the valves.
Before this derails anymore, I am going to guess John isn't wanting an all out race car anyway, more of a nice, peppy driver.

And that is one of their better qualities.

Slant problem: the cars don't auction for $80,000 like the 1968 Camaros. People with $5,000 cars don't spend $4,000 on the engine.

I made /6 parts for awhile. During that time I met one guy who was willing to spend money to buy good stuff.
