One thing I've learned is that you can save money buying inferior parts but you risk is exponentially increased that in the end your going to spend double to repair.
Might as well go buy some of those eBay knock off rods and pistons too.

MORE THAN NOT YOU PAY FOR WHAT YOU GET IN LIFE. Then putting not proven parts on a F/I motor you are just going to be asking for problems. Just my 2 cents out of a guy that cant make a sentence. Robert

I posted this thread with the intention of hearing from anyone that has had EXPERIENCE using these heads. So far I have heard good things about these heads and the only negative things I've heard are just opinions from a few people because they are made in China.
So until I see true negative results of these heads failing in some way, I am going to use these on my new build because they are said to flow really well. Thanks to those who shared info on these heads. I will post later on how these heads perform!

Used a set on a 421 sbc., bought them bare while they were a bit ragged around the bowls and runners, we cleaned them up with some china made tooling and they performed as well as the previous canfeilds. Nitrous was the power adder.......no first hand with a blower.

Casting could crack due to poor casting method, quality control, or crummy mix of alloys.
Valves could break due to just being cheap crappy pieces or due to head design with bad valve control.
Very risky running a set of heads on a brand new engine that have little to no data available on them. Especially with better options available.

Keep in mind buddy, those pretty new LSAs you just ordered were made in Mexico! Looks like you may be taking some risk yourself!

On the other hand, I have been able to find NOTHING on those heads and there durability/reliability in a high rpm big boost situation.
It's not being a leader, it's called gambling. And based on the nonsense earlier in the thread and other threads related to your build, it doesn't sound like you have money to gamble with.
Hope your budget heads don't end up doing this to your engine.

Ummm... Yeah, I don't think there is any risk actually. They were designed for boost from the get go, are made from a premium alloy, and use a advanced casting process. The combustion chambers are smooth as silk... Not to mention, they have been on a factory forced induction engine for years and I have yet to hear of any head issues. Plus I will be using Manley extreme alloy hollow stem intake valves and inconel exhaust valves. Not some random junk that is probably heavier then a freight train.
