So I made a nice purchase this weekend. Got a flat-top and a hex-top head for next to nothing. Grabbed the distributors and a few misc. parts too. I didn't really need them, I already have a flat-topped log head I've been working on. But for the money, and to save them from being scrapped I had to take them home. There's a real nice low-mount starter 200 and a 250 block left behind, dirt cheap or even free to the first guy that gets there soon enough. There's more details in the eBay deals. Anyway, after looking at the two heads, I'm wondering what to do with them. The hex-top has an obviously larger log, the end plugs are 1-1/4" vs just 1" for the flat-top. Someone said in another posting that despite that, the hex-top head has smaller ports than the flat-top head. I'm not sure why Ford would do that when all the other changes were about easier flow, maybe to get the air velocity back up after slowing down in the big log passage? And there doesn't seem to be enough material on the top of the hex log to support milling it off to add a two barrel carb mount. So what I'm thinking, and looking for correction if I'm wrong, is that the hex-top log might be better if you're planning to stick with a one barrel carb, or maybe a one to two barrel adaptor. But the flat-top log is better for a full two barrel adaption.
