[@robinator503]

Beautiful work

[@headgames]

Thanks

[@GTRliffe]

Heads-gains right there 😜

[@myrx2]

Be interesting to see what can be improved on a vw golf R head

[@headgames]

the EA888?

[@myrx2]

@headgames either the ea888 or the older ea113. I know the later ea888 has the manifold cast into the head which makes things even more difficult. Just haven't seen many actually do proper testing on them.

[@headgames]

@@myrx2 we do both of those, but not enough to warrant flow testing, but we can do it when they come in next time and put it on KZbin

[@myrx2]

@headgames that would be absolutely amazing if use could. Ive searched everywhere on the internet. Old forums and social media for flow numbers both before and even after to see if there was any viable gains but couldn't find anything other than photos of work people have had done and even then they had no answers other than "my mechanic said it will be better" im sure there would be gains to be made in a drag style setup but thats useless for a daily street car.

Please do N57 ❤️

[@headgames]

Never seen one. Or heard of it.

[@maximilianlindner]

@@headgames It's the 535d's engine. I guess they're less popular in the States though.

[@adamyearsley1204]

Super interesting thank you. Any secret sauce porting tips for a na bmw m42/44?

[@headgames]

I got nothing on that.

[@Tezworx]

Why is it that you guys don’t do VAG 2.0tfsi heads ?

[@headgames]

The 5 valve?

[@Tezworx]

@@headgames the 16 valve ea888

[@myrx2]

​@Tezworx dont forget the ea113 aswell lol The ea888.3 head is hard to work with since the exhaust manifold is cast into the head. The gen1 and gen2 heads would be cool to see get a bit of a work over.

[@headgames]

@@Tezworx we work on that head. We have done a few.

[@gsturnerjr]

Ive watches your process, wondering if you remove the guides for access (esp 4v heads) or its part of the valve job.

[@headgames]

We remove them to gain access to the entire port and because the bronze has a natural lubricant while also dissipating heat better than the steel guide. And lastly, we are also installing aftermarket valves, with the bronze we can run a tighter tolerance. All upsides. The valve job needs to be machined after the guide install. Great question!

[@gsturnerjr]

@@headgames on two valve heads it seems the guide is the sculpted for flow, is the four valve guide, because of the smaller stems, just not such a big obstruction? Great content & information.

[@headgames]

@@gsturnerjr the 2v guide boss is so much taller and integrated into the port vs a 4 valve it is just easier to remove it in order to widen the short turn. Hope that makes sense.
