Sodium hydroxide is environmentally safe, easily neutralized and very commonly naturally occurring.

Lye in the concentrations used in a hot tank will fully dissolve a human body in a matter of hours, not something you want to mess around with. I lost a layer of skin and my finger nails after a few minutes of contact due to a hole in a pair of rubber gloves. I’ve spent a lot of time around hot tanks, and I fully understand why they are not as common now.

You can clean aluminum with lye, but it’ll become toxic and a hazardous waste to dispose of, and you can only use it for seconds/minutes before it starts to dissolve the aluminum. Another reason it’s not used as often as it once was.

Lye/sodium hydroxide is a great cleaner. Safe and environmentally friendly (after cleaning engine parts) it is not.

If you want an 8V head with superior port design. You want to get your hands on an EVO head from ACM.se https://acm.se/category/634/product/ACM-1607
It's just fun to browse their site with all the good stuff they supply.

Yah, those EVO heads are impressive. When I get around to a turbo B230, I’ll keep it mostly stock, around 250 hp will be way more than enough to amuse me in a little 1800ES.

Yeah, I use the harbor freight cleaner in my parts washer , it’s NaOH and various surfactants , works really well. But even at those lower concentrations, it will attack aluminum within about 1/2 and start pitting it.

Yeah, a normal sized engine hot tank will use 150-200lbs of pure lye to get the cleaning speed needed.

That will strike the nice balance of power and what the chassis can handle. Great project Andy!

I’m just working on the B20 now, Doing a modest build on that with ported head, TInus Tuning TT4N head , and modern ECU.

Just want to get the car running and driving so figured the B20 was simplest.
