Doing a rebuild '73 2.0 motor - heads are shot Options

[DC_neun_vierzehn]

My '73 2.0 motor needs a rebuild. Different shops are recommending different approaches to replacing the heads, which are both cracked (near the spark plug holes).

One shop doesn't believe in using "Chinese crap" and wants to try and search the planet for NOS or great condition heads, but has no leads (nor do they think welding/repairing my heads is a good idea).

The other shop is open to using high quality repos like the Len Hoffman 2.0 heads.

What have folks used for replacement heads on a 2.0 rebuild that are performing well years later? Are there any options out there for finding NOS or top shape used 2.0 heads?

FYI - keeping the motor stock - no mods on the rebuild.

Thanks in advance.

I am having a 2056 built by European Motorworks and am using AA bare castings. They will be replacing the seats because they don't trust the seats they come with. The 2 liter heads flow better and have a more desirable spark plug location. Yes, they are more susceptible to cracking, but I am not concerned about it since I am using new heads. If you are concerned about cracking, you can have additional material added to new or used heads and go with a 12mm or 10mm spark plug hole, as was suggested. I didn't go that route because I didn't like the idea of adding material(and heating up) a new head. As far as I know, Len at HAM is using AA or AMC castings and improving them and is only building heads for sale via the Type IV Store. Somebody can correct me if I am wrong. If Len isn't using used heads, I wouldn't either...50 years old and too many heat cycles; but then again, he is a builder and has to stand behind his engines, you just have to sit in front of it.

You mentioned keeping the motor stock, but consider going with 96mm P&C. It's a nice upgrade and you can keep your stock FI.
