I was discussing with a friend about my idea of putting an AU head on the EA (it's an ED engine).
I know to put on an AU gasket etc... although there is a vague memory where someone on here suggested boring some particular bit out of the head (remind me if you know who you are - I think it was to get something out quicker and improve efficiency?! : Blonde moment). So anyway, what is the difference btwn the EF/EL head and the AU head? And what, in your opinions, is the way to go? I am not really chasing performance, but I don't want to have to keep doing the head change too regularly. I want to know that once it's done, it's done for a few years. Note: It's dual fuel too, just letting you know in case it makes a difference

If you are running duel fuel, you might want to try and find a AU Egas head, cam and rocker gear.
The heads aren't really the problem in eseries engines, it the gaskets that were used. By using the AU meatal gasket this fixes the problem. When it comes to doing preformance mod to heads it becomes a diffrent issue all together. |

EA/EB/ED/EF/EL ran a rocker ratio of 2:1 and AU ran 1.8:1, you can bolt either to any head, but you must use ea/eb/ed/ef/el cam and rocker gear (any combo is fine, I run EA head and EF Cam), or au cam and rocker gear together.

Ahhhhhhhhhh! I see!
I have organised the AU metal gasket (of course, nice new head bolts) but is there any point to just replacing the gasket? I have always been under the impression that while the head's off you should get it reco'd (or replace it with one that already has been). Basically it's because there may be an unidentified issue with your old one so by reco-ing it you can be sure that the head you put back on is in good nick. And nobody wants to go to all that trouble and then find out they should've replaced the head after all... AU egas head? What's the differences in that? Very curious...

You can use the same head. Just get it machined and crack tested etc. Should only cost a bit over $100. If it's cracked, you'll need to replace it or reco it $$$$.
Bindi, I just took a head to get the basics done (crack tested, machined etc) and they identified a crack. I was quoted $330 to weld the crack, and reco the head... Or $440 exchange :S

Gas head likely to have valve seats designed for the poor lubricating properties of LPG. Maybe slightly higher compression.. I thought EGAS was BA-speak?

I am losing a bit of water but not sure where... thinking it's either the heater core or the gas system... or maybe the head after all. I just don't want it to break down, I want to prevent this from becoming a major problem and have to replace the engine (been there, done that).

The AU egas head, has higher compression, and runs bronzed valve guides, HD gas valve seats, and the cam has been ground to suit gas.
For around $350 you can get your head fully recoed with all the above work done, except for the cam. A regrind from wade for gas is about $120 |

Do you know when your EL was built? Supposedly later ELs had a hybrid engine, with an AU head.
So it should definitely be possible. No idea if the volumes were different. You would use the AU head gasket. And the short answer on the cam is no. Supposedly different journals/ rockers/ pedestals. (I have heard of guys making it work, with a combination of parts, and it runs, but sometimes they break things. And if you get it wrong, it's bent valves or worse.) |
