I have a set of the original SBC Twisted Wedge heads in the shop now. While I think the idea of the tilted intake valve had promise, I don't think it panned out as well as was hoped. To take advantage of the heads, different pistons were needed and I don't think the advantage was worth the cost of designing and producing them. In other words, There just wasn't enough gain over well-designed "normal" heads.
My guess would be that they are probably more successful than the SBC heads. Perhaps it's because there is a little less competition in the Ford head arena. Somebody with a flow bench could check it out.
so, I would also need a set of matched pistons....
I think that I'll stick to the newer heads..., which doesn't need special pistons...
Thanks!
