None of the aftermarket heads have ideal seats for Ti valves. If you had high thermal conductivity seats installed, the cost would be really high. Yes, you can get by with ductile iron seats and Ti valves, but the durability will be lower and possibly much lower depending on how the car is driven.
Mamo heads would be awesome but out of my price range, the guy I quoted below has sound reasoning about WCCH BR7's. I am staying NA and starting to want to stay with the stock castings lol.
That makes sense, I contacted WCCH yesterday on their stage 2 job on my stock castings. Right now I am looking at turn around time and AI, WCCH, and SPS Cylinder Heads are on the top of the list. It all depends on turn around time when my Z is being pulled apart at the end of the month. I am not planning for boost on this car, NA until she cannot move anymore lol. Once the engine starts getting weak in I do not know how many more miles, I will pull it for a built 440/441.

Just popped my PRC 285s off. They look amazing. Valves are tight and nice, no wiggle after 30k+ miles at 1000+hp and .655 lift. Debating just cleaning them and throwing them back on, or going All pro/Mast with crower/shaft roller setup.

Bottom line: Mamo heads are comparable to other aftermarket casting prices, more than some less than others.

Brodix spec'd out like my PRCs are $4592 and that isn't even aftermarket intake valves.
Tough decision for me, as my PRCs have $1200 just in trick brand Ti intake valves.
Probably going to drop them off to get cleaned up/inspected, then go from there.

I am looking to buy towards the end of the month or in a couple of weeks. I am starting to go away from wanting PRC's, I asked on FB and people were sending me pictures of head failures. I think I will go with some BR7 heads.
I heard the TFS's stock were not really great? I read where you should have Mamo do them or they are a waste or something. I have yet to see results from stock TFS's.
No horsepower gain from WCCH stock heads vs WCCH Brodix heads? I am looking at Frankenstein BR7's now, they look like they are making big power.

What failures have you seen? The only issue theyve had with the LS7's are the springs as someone else mentioned. I'm making 601 whp with 285, 1 3/4 headers and a ported GM LS7 intake

That poor zrod only had the 80 mile drive out there, and 4 passes on it. I was annoyed having to dump good oil.
Part of the game. I don't know of anyone else that has got that type of use out of a motor. Sadly I was planning on pulling it and doing a refresh. Lesson learned, 1000+ hp cars should be pulled apart at least every 25k or so. Next motor will have a PM schedule where it gets yanked at least every 5 years.

Understood. And yea that is too bad about the oil. When my motor let go I also had literally just changed the oil too and I was more pissed about dumping good oil than the broken ring land I found in #7. Made a change to my # of track hours refresh schedule also as a result.
I honestly don't know of anyone (and I know alot of people in my area with big hp cars) that got the use you did either out of a 1100hp+ regularly driven and raced car. I'm honestly amazed it held up this long.

Everyone always writes “Mamo is too expensive” right before they mention that they will prefer another aftermarket head. Mamo heads are $3900-$4000 without options but can be stage 2 ported for several hundred more. How much are the BR7s?

On a ls7 casting?
Even if it was, a one off freak failure shouldn't rule it out. If that is the case, then no heads are good, and no block is good.

Claimed it was their PRC 285 head, I am not ruling it out for that reason though. I decided I did not want to spend that much and I am going with WCCH. I can also retain the stock TI intake valves.
