Differences between an E31 and E88 on a L24

Well, it seems my E31 head is too eaten up by electrolysis to be cost effective to repair. I was able to get what appears to be a good E88 head from a friend. Are there any differences I should be aware of between the two heads on an otherwise stock L24?

Should work fine. What to watch for is the exhaust valve size and cylinder wall clearance. Depending on what e-88 head you have you might be taking a step down in performance. The early e88 is the better head. Did you get a price on fixing the e31?

Thanks Steve. I believe the head came off a '73. Does that sound right? The price on repairs for the E31 is going to be way north of $700

So, after searching, if I'm correct, the early E88 head has the same size exhaust valve as the E31? If the E88 I have has the larger exhaust valve, I guess I'll need to notch the cylinder?
