The S54 is a sexy motor!!!

Thanks for the offer but I am trying to declutter. I hope you are well!

I an E28 project waiting on some attention

What year 535i?

I will defer to Stevej on a recommendation

So basically they pick and choose what they list. They get to cherry pick; it's not really an open market. Too bad..

If they're tight and look ok with good boots, I might run them for a while. They will get replaced eventually if you put enough miles on it

I guess the biggest thing is figuring exactly where to tap the carbs

That's a good question! I don't know. Part of the problem is using something that prevents further rust with out locking up the pivot points. Maybe treat the area with a conversion product and then keep it lubricated to prevent corrosion...

How close were they to what it's really worth?

Lye will evidently clean the burrs of aluminum and beeswax is said to prevent build up but not contaiminate

I have some for aluminum and they have a different tooth pattern. I have seen a tip on how to prevent this but can't remember what it was.

I have a selection of carbide bits like that, but those little metal splinters go everywhere!!!

GLWS!

BTW, count your blessings. My daughter wrecked one of my vehicles again this week and flattened it on the back of a 2015 Lincoln. It could be worse!

Zcardepot is $122 Zeddsaver is $120-160 with the rings there are some decent prices ones on Ebay search for "240z gas cap"

I use a die grinder with a 3" cut off wheel to dress welds down most of the way. Then I use die grinders with 2" & 1" rolocs on them 36 grit. Sometimes I finish up with a 4" flap disc, but the flap disc can remove a lot of metal really fast and there is not a lot of metal thickness to start with.

It took a lot of work and is pretty creative, but that doesn't necessarily translate into value!

Facebook marketplace has become very popular. My wife does the marketplace stuff for me

I expect it will be a larger event than normal

Yes, that is my understanding. The heads I have seen done are stripped clean of all the valve train and dressed on both sides. you end up with two flat perfectly true and parallel sides. Otherwise you add distortion to the cam. Also I haven't ever seen a milling machine that could mount a head with the valve train installed or a situation where you would want all the milling chips strewn throughout the valve train. I might be mistaken on this but this is how I believe it is done.

I believe, that most of the machine shops I know of true both sides of the head when they flatten them. So that the towers are straight and true

That's great progress!

They are evidently available in the US at the Tire Rack. I don't know if the specific size is available though
