I know exactly how hard you are trying to tell the people how to handle the tools. it's very hard to explain and I Appreciate your patience to tell it over and over and over again 🙏 I learnt a hell off a lot from you dave. you can't reach everyone but you reached me and I am heavily addicted to porting. when you notice peterns you see potential power everywhere. keep it up for your cnc - big support from Germany
@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 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.
@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.
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!
@@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.
@@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.
