Red top in the ae86

Just to confuse things a bit more........

The 1st gen largeport (1984-1987 **IF** original) is different from a 2nd gen largeport. The most obvious sign would be the front of the head - the casting is different. If you look down at the front of the head you'll either see a small gap between the cams, or not. The gap means a 1st gen head. No gap - 2nd gen head.




If your plan is to build a standard valve head, I'd strongly recommend using a 1st gen head, as the casting is also different at the bowl! The 2nd gen head is better for a big valve head build.
