Yeah I went to quite a few machine shops before I found one that was willing to do so haha. I'm pleasantly surprised and impressed with his work. I only wish I knew how to weld like that.

I'd be willing to bet the HF on his TIG is permanently set to "MAX CLEANING"
Did you list the shop that did the repair work. Think they would tackle a set of vintage Ferrari heads?
Also those castings look seriously "Italian"

I did, the name is M&B Cylinder Heads. They are out of Portland Oregon, ask for Brian and tell him Derek, the guy with the Lamborghini sent you. I'm sure he'd be happy to tackle a set of Ferrari heads. Just keep in mind his rate is $100/hr. I'm 15 hours into each of these heads right now. Then again, hopefully you're not dealing with the insane amount of pitting mine had. But I would absolutely trust him with oldschool heads.

$1500 for properly repaired heads? Worth it. Not even that bad, really. Have an estimate on how much work remains?

It is my understanding that a good set for the car is ~20-22K so 100$ a hour should not be to scary.

Yeah, I agree. That's per head, but still... one head last I checked was about $6000-6500 a piece. I haven't looked in a while but regardless, it's cheaper still than new heads. As others mentioned, it's still likely there will be weird imperfections in the old alloys too because it's likely it's going to be NOS.

Yeah, that's a drop in the bucket for something that expensive. What model of Ferrari is it? I love Ferraris and would eventually (after the Jalpa is done) start working on an older Ferrari.
If these guys are anything like the place I told you about (Eriksson Industries in CT), they will keep going until the head is flawless. If anyone works on cars with aluminum engine parts from the '50s-'70s as a habit, they HAVE to know someone capable of doing this. Good you found someone on the west coast.
Also, I think you'll find your repaired head will be less porous than an NOS piece. I'm surprised at the casting porosity. I've seen a million FIAT 124 heads and they never looked like that. Triumph / early-SAAB 99 heads, yes.
Wow. Finally remembered to look this thread at home (pics are blocked at work).
Wow!

Same here ... Wow indeed !!
I get to work with current production cylinder heads all the time, and have seen many pristine looking castings fail leak test before being impreg'd with whatever magic goop (epoxy mix, I think) they use to seal the mild leakers up.
Wonder if you could get vintage heads impreg'd as an extra measure of safety after seeing all that porosity ?? No clue who would offer that service on the aftermarket side, but it is quite common for current cast aluminum production parts.

You might want to check out this guy for your Ferrari heads.

Good ol' JB Weld works well on the mating surface. Just bead blast the surface, clean, and apply. No need to sand. Just have your machinist mill the whole surface flat. Unfortunately, nothing works in the chambers.
I'm glad you're all enjoying the project and thanks for the words of encouragement. It's coming along. So hopefully, so long as things stay on schedule, I may have my first start this summer. Though I'm not going to put a deadline on it, more of a goal, and take my time and ensure it's done right.
Can't wait for the startup video, I want to hear that Lambo V8 sing.
Picked up the heads yesterday. They're tucked in all nice and cozy at home. Come this week I'll drop them off at the machine shop that'll be doing the flow work, and it's finally time to ORDER TOP END PARTS! Probably also drop off the block while I'm there.
Also, for the sake of contrast of before and after...
After Brian touched them. You can see that the factory alloy is quite porous, but if you notice the areas he welded up, it blended very very well.
Pretty !!
Holy berk
Is that factory porosity going to be a problem?

Nope. Should be perfectly fine. Everything is sealing just fine.
Wow. Those are incredibly E36 M3ty castings. The work looks really good though!
Seriously? Not one comment on how $100 an hour for good head is worth every penny....? I am disappoint in this crowd.
Head work. Sorry, I meant head work.
In reply to pinchvalve:
I agree that those rates are phenomenal (for both of the things you said 
)
