Hudson- you share my opinion on relieving the block. I discussed it at length with a flathead Ford guy, and then again with a friend who is quite interested in my flathead six project. Both thought the flow was paramount, I figure trying to get an L-head to flow (in modern terms of capacity) is like kicking a dead horse. I opted for compression rather than flow, but I thought I'd toss the idea around one more group. Thanks. The Edgy head is done by a guy named Earl Edgerton, you can get ahold of him at

I do not know if the Edgy head is more similar to a Fenton or an Edmunds head, I searched for either for years but could never find one. I also tried to get a Phillips head when he was developing his, but was never able to get one. I don't know if he ever produced them finally or not.
