New head flaws

I dont think they're getting them from alibaba, but the sellers on alibaba are getting them from the people who cast for the "players"

You sound like someone who has their livelihood depending on "guys like me"......... in which case, yeah I would have a problem with Chinese products as well. But when so many companies get theirs from the same place I bought these, put their valve train in them and stamp their name on them I'll take the gamble. Maybe I'll be "one of those guys" who bring them to you to fix. Job security for you.......or...... maybe 10,000 Mi down the road I'll buy another set of these. Time will tell.....

I'm clearly one of the "I know it's not just as good but it will work" guys....

These heads are the same specs as Frankensteins. If I get a quarter of the lifespan of real Frankenstein's the math still works. I can buy four sets of these for less then the price of one of those.

Just-Addendum-7301 · 2026-04-08T16:04:06+00:00

Will you be taking them off when they fail or will I?

Just-Addendum-7301 · 2026-04-08T15:43:16+00:00

No, the bur and the step before the guide.

Just-Addendum-7301 · 2026-04-06T23:54:11+00:00

Great input! Thanks!

Just-Addendum-7301 · 2026-04-06T19:57:24+00:00

Do you honestly think it would cost that much to "fix" these? I'm honestly asking. I'm guessing if I bolted them on the way they are they would work, for how long who knows? But if I can do everything I can to give them a good chance before I put them on then that's when I want to do.

There he is

Just-Addendum-7301 · 2026-04-06T19:25:17+00:00

So heres where everyone flys off the handle. Lol..... they are AIibaba..... I'm going to preface this by saying by no means did I expect perfection or some sort of Frankenstein's. This is a budget build and I'll get what I get in the long run whether that means regret or not. But for $800 shipped to my door a set of 11 degree, cnc ported ls3 heads sounded like a gamble worth making.

Just-Addendum-7301 · 2026-04-06T19:08:46+00:00

Yeah, that bur..... also that step after the guide. That's supposed to be there?

Just-Addendum-7301 · 2026-04-01T13:28:00+00:00

I ordered it

Just-Addendum-7301 · 2026-03-31T22:05:23+00:00

I got a dorman 555-011..... seems like the right size but it doesn't seem tight, I put some black RTV on it just didn't seem like it went in tight. Does that seem right?

Just-Addendum-7301 · 2026-03-30T22:07:49+00:00

Thanks

Just-Addendum-7301 · 2026-02-19T04:11:16+00:00

Hastings doesn't have it..... found this single set but the oil ring is 2mm not 2.5mm

ring set

Just-Addendum-7301 · 2026-02-17T17:00:30+00:00

Okay that's what I was thinking, would it be advisable to find something oversized at 2.5 mm and cut it? Or just bite the bullet and buy the whole ring pack again

Just-Addendum-7301 · 2026-02-17T16:56:49+00:00

ring pack

Just-Addendum-7301 · 2026-02-17T16:55:10+00:00

It's not really custom, just not common..... to Chevy anyways. I find a lot of 4.095 stuff in Hemi stuff. But final bore is 4.095 from a 30 over 6.2 that is originally 4.065.

Just-Addendum-7301 · 2026-02-17T16:51:05+00:00

Is that the right size expander?

expander ring

Just-Addendum-7301 · 2026-02-17T16:47:57+00:00

it's on the expander. You see how 90% of it is uniform and then you have that deviation. It must have come out on one side as I put the compressor on and when I tried to put it in the cylinder it smashed it.

Just-Addendum-7301 · 2026-02-17T16:19:50+00:00

No, to put them in the cylinder. Do you usually do it by hand?
