So, I sold me EL1 head that I got from Mike (Guyhatesmycar). It's going to go to Xvok. I'm pretty stoked that someone in town is going to be using this head. He has an '82 Accord, and had the head off. So I was able to take Mike's '83 EL head and match it up to the '82 Accord EK1 head gasket. Everything lines up perfectly! Even the manifolds line up. Finally, we know for sure that the swap is possible... JUST MAKE SURE THEY'RE THE SAME YEAR!!! (82 and 83 will interchange)
The dirtier looking head is from the US '82 Accord, and the clean one is from a Canadian '83 Accord.
Here's a top view. Everything looks like it lines up this time!
The intake ports are the same, same size and layout. Just missing the CVCC ports on the Canadian head.
The combustion chambers appear to share the same bore size. And the chambers themselves look the same size. It doesn't look to me much like the Canadian EL head will actually raise compression. The valves look to be the same size as well. My guess is that the 1800 EK bottom end is a stroked 1600 EL. You can also see how the spark plug holes are directly in the combustion chamber in the EL head, replacing the Auxiliary chamber.
The final test was really to see if the US headgasket matched up onto the Candian head. And as you can see here, it does.
And finally, here is the new head, in mad tyte Type-R color configuration.
As rjudgey says, I'm a headophile.
