E31 head - are they still desirable?

[T-Bone028]

I know there was a time when the E31 head was the hot-ticket for cylinder head choices. It seems now a days, because they are more rare ($$$) and other heads can realize the same flow characteristics with a little work, it seems like the E-31 is only desirable to folks that are limited by certain race classifications.

 

I have an E-31 head just sitting in my garage...I feel like I should keep it, but at the same time I know I will never use it and it could be used by someone else. Whats the consensus on its desirability? Whats a fair price to ask if I were to post it for sale? If this is in the wrong section, my apologies.

I think it is desirable to ITS racers because it ups the compression a little bit over the other heads. The Z is becoming less and less competitive in ITS. You can look around and see what they're going for, but if it's just a stock E31 that needs a valve job and all the rest, my guess would be that it's value is about $150.

I know Jimmy Caselnova raced SCCA GT2 for years in his tube frame purpose built Z32. Not sure if he is still racing. He only uses E31 heads and F54 blocks for his motors. Dry sump, 13.5:1, 300+HP. Not sure why they use E31 heads. Jay Gurtlinger from Bob Sharp racing builds his engines an dcertainly knows what he is doing. In the races I've seen he is as fast as GT1 cars. Pretty cool considering most of those GT1 cars have 500+ HP.

Thanks for the input guys...its what I figured. Desirable to those that need it for race applications limited by class specifications.

 

I guess one of these days I'll put it for sale, until then, it will have to sit in my garage and constantly be in my way.
