Parts you blindly trust to be good to go from the manufacturer are exactly the ones that are going to prove you wrong in the end. Always check and correct.

Hey Eric you ever get a set of Proheader ls1 heads? They look and seem to flow like the Dart 205cc but they are 210. They use Qualcast valves which are supposed to be like OEM ok...

Even if something (anything) is from the same factory as the US branded item, doesn't mean the quality is the same. When factories produce goods for a US specification, they have to meet those specs (within spec tolerances) or the brand will reject them. When that factory sends those same goods out the back door, they don't have to meet any specs, and probably are even measuring them.

@bovineknievel410 11 ай бұрын

Absolutely. In fact the ones that are rejected are often the ones that end up being sold out the back door.

@jesuscobos7243 7 ай бұрын

I refer to these as just a bear cast head since they still need a good port job and machine work to be actually any good

I bought from Ebay heads that look exactly the same. I had all American parts put in and the heads surfaced before installing on a 383 SB. These heads are 202- 160 values and 68 CC combustion chambers. The heads went on a 383 using 6 inch Eagle connecting rods for my Chev 1988 1 ton for a work truck for towing a large boat and for a hunting truck so absolutely no racing hard uses.

@perryroger21 11 ай бұрын

I’m building a set of these heads right now. I’d disagree on the valve seats. I lapped in Elgin valves surprisingly quickly. They hold vacuum really well. I’d agree on the deck surface though, mine also have a bump in that area. Thanks for all the helpful vids!

Just for reference not disputing anything but this tidbit. We can feel as small as 10 to 40 microns. But .003 sounds about right for the difference of passes on aluminum. You gotta cut in one pass.

I bought some of those exact china heads, a while back. In the end, I gave up and sent them back. Replaced them with AFR enforcer 195's lol. I can attest also, they are NOT the same at all. You will spend more money making the China junk usable than what it cost for the AFR heads that are bolt on and go.

By the time you take it to someone to port you might as well buy the cnc heads or just AFR enforcers already finished! But I agree you just can't take Fleebay or scamazon heads and put parts on. They need to be checked by a machine shop that knows what they are doing to make them reliable! You spend 500 dollars on heads and then 4-600 on valves, seals, and valve job, machining and you are right up close to the cost of AFT enforcers!

I don’t buy from DNA, literally buy from the casting facility for AFR/dart/summit. DNA does their own machine work, so no, this isnt Chinas fault, it’s DNA’s fault.

@WeingartnerRacing 11 ай бұрын

Ahhh these heads are machined in china. If you buy the AFR enforcers they are also completely machined in china not America. That’s how they come from them. To my knowledge they don’t sell them unmachined. If you are saying you get them that way that is the first I have ever heard of.

@billythebake 11 ай бұрын

My question is how good are the material used in the head castings, guides, seats, etc? My experience having sourced things out of Asia (albeit 35+ years ago) is that you cannot (CANNOT) safely assume that two things that look alike truly are The people over there know how to cut costs on things, and they very commonly will do it on materials A set of patterns that will cast a part in good virgin A356 which is then heat treated to a T6, can also be used to cast parts out of recycled beer cans with whatever level of heat treat is considered cost-effective by them On top of that, a set of casting patterns that didn't meet a customer's spec might be used to make a part that looks similar, and is used to compete with them in the marketplace This isn't theory, this is stuff I've seen. Personal experience. Don't know if it's the case with these head castings, but it's just the kind of stuff to look out for in general... When you buy something sourced out of Asia, but you buy it from a reputable US-based seller, a lot of what you're paying for is QA

@xozindustries7451 11 ай бұрын

Ya, once you buy them, send them out to get all good parts installed, a valve job, surface the head how can it be any cheaper than buying AFR enforcers, ect?

Does the cost of the out back machine work outweigh the upfront cost savings? To me, that's a great point to have a clear answer on .

@firebirdjone 11 ай бұрын

Eric could give an in depth answer and I'd like to hear his thoughts but in my experience to your question........no not really. By the time you buy the good parts and then pay the machine shop to do all the work to get the heads up to a level I'm satisfied with, I end up spending anywhere from $1000 to $1500 on top of what the heads cost initially. Personally I avoid the Chinese heads and prefer to spend extra upfront for AFR, Brodix, or Trickflow. Even then I still have them looked over for valve job and valve guide clearances and spring pressures before I run them on an engine.

It'd machinists like you that people should stay away from. You can take those cheap heads and have them worked and still be in for less than half that what AFR or Dart heads will cost you. Not everyone has the deep pockets to shell out 2k on high dollar heads. Those heads are clearly not the best heads but you can easily get 500 hp out of them and 80% of people, that's enough for their weekend cruiser.

@WeingartnerRacing 9 ай бұрын

So pointing out obvious flaws is the wrong thing to do? You are right bolt them on and have a head gasket leak and valves not seal at least you made 400hp. I promise after rework they are more expensive than the afr enforcers.
