[Livernois Motorsports]

Building an engine? Want to take your coyote engine to the next level of performance? Livernois Motorsports has What you need!

It is no secret that the coyote platform hit the roads in 2011 and has blown people away with its performance and power numbers, this can be largely attributed to the 4 valve dohc tivct cylinder head layout these engines use! While the 5.0 might be smaller in displacement than the competitors, it still packs a big punch.

This is where Livernois Motorsports comes in! We are able to improve off the already amazing heads that ford provides and get them to flow even more air and make even more power! We have spent years doing R&D on our own vehicles in order to present to the public a proven cylinder head package that is sure to get your coyote equipped vehicle to the next level.

We use only the highest quality components when it comes to our Cylinder head packages! The stage 3 Cylinder head is our top of the line offering for the coyote, it features the following:

• 5 axis CNC machined
• Fully assembled w/o camshafts
• Custom CNC valve job
• Custom Ground Stainless Intake Valves
• Custom Ground Stainless Exhaust Valves
• Custom Valve Springs
• Stock Guides
• Upgraded valve seals
• TI Retainers
• Stock locks

All Livernois cylinder heads are designed, engineered, and manufactured in-house at our facility in Dearborn Heights, MI. 100% American Made, built by the automotive enthusiast, for the automotive enthusiast!

What are factory head flow rates?

 

[VictorH]

Thank you for posting. Since you are promoting your product can you provide information on the following:
1) Do you rework the chambers or is it just a polish?
2) How is the port velocity compared to stock? All cylinder head folks (generally really ALL) publish flow numbers but almost never velocity. As was shown long ago by Smokey Yunick you can have big flow numbers with lousy velocity and end up with mediocre performance.
3) Why retain the stock guides? Probably a good reason, but some of your competitors switch to silicon-bronze.
4) What rpm limits does your spring and retainer package tolerate?
5) How much lift does the stock camshafts generate and what's the flow difference at stock lift between stock and ported heads?
6) Do you have dyno proven HP numbers for these head compared to stock?
7) Is this more of a drag-race type head or could it be suitable for street or road-circuit track uses?
Would be interested in as much information as you can provide.

Also, what is the upgrade to the valve seats other than a nice multi-angle valve job?

 

[Livernois Motorsports]

to answer the questions asked on this post:



The heads do lose some velocity.

On a stock n/a application no boost you can gain up to 20 hp

gen3 stock cam valve lift is around .504 intake .504 exhaust.

The chamber on the stage 3 heads has a bowl blending program/ polish program, we do not reshape them.

we have taken our valve train components to 10k RPM

The reason we use a stock guide is because these heads are intended for street/ strip use. When switching to a softer guide you significantly reduce the life of these components. so, we use a stock guide on this application however we can custom spec heads out per the customer's needs

these heads are used both on street cars to some very serious race applications

In other words, unless you're shooting for 1300+whp and running 7's, continue using stock castings.

No, There is still a benefit for using these heads. n/a the gains are not very high, but with a blower, you will benefit off of these heads. Keep in mind the coyote heads from ford are very good, we are able to refine them and bring you better components than stock while also gaining hp.

Yeah, not very fair to crap on this product simply because what you started with was already good. I would wager this is a very nice addition when you're using a turbo setup.

What gains would these add if you were running ~10 psi boost?

 

[VictorH]

I think these are nice heads. However, the main point in my view is how good the stock heads are in terms of flow and performance. Let's just take that they are good for 20 HP gain for n/a application. So, we're netting about 3 HP per cylinder which is VERY modest. Kudos to the Ford engine engineers for the out-of-the-box performance.

 

[Cory S]

Only good for max effort setup period. The port velocity loss/lower TQ on the street isn't worth the cost/gain IMO.

Like I said..... For those wanting/NEEDING to go above 1100whp and track/drag race these heads sure.....

 

[Livernois Motorsports]

you would gain up to 30 hp.

Exactly. The stock heads are great and so are the cams. This is the reason I love coyotes. LS for example, in order to start making any decent power you need to do heads/ cam, get rid of the dod. Ford gave us a wonderful starting point for these cars!



20 hp isn't Earth shattering but, if you are looking to squeeze all you can out of your car, doing the heads is a good way to do it, also you are using components that are "Billy Bad Ass" and have been tried, tested and proven by us on our own shop cars.

When it comes to people wanting to get the most out of their cars, these heads are up your alley, n/a people going with a CJ, headers, cams, converter ETC can benefit from these, really anyone can. it's obviously not the same money as doing a tune and a cold air but some people want to keep putting power into their cars and this is a great way to do it, especially if they are shooting for upper rpm power where the coyote shines! These heads are streetable, we run them on our own shop car that we drive for car shows, cruses and we run it in the 9 sec true street class.

Not saying its not a good head for max power, but they surely aren't for the average Joe. It's a tough sell. We know this.
