Thanks for the explanation. I understand, but there would be weight and heat advantages, as well as possibility for making improvements for intake, and exhaust flow. I’m saying for a street car, not racing applications. It just seems like for mild upgrades it would be beneficial overall. But again maybe I should keep my trap shut, cause I definitely don’t know enough to be trying to sound like an expert.

The biggest problem is, the slant six head was designed around one engine. The 170. So, you have a 170 flowing head on a 225. I am not an expert either, but that's a lot to overcome. Even starting a new head from scratch, I am not sure a designer could make it worthwhile with all the costs involved even for a mild street head. I wonder what it would cost to design and build? Then put a reasonable enough price on it that they would actually sell. From my very recent discussion with a pretty renowned porter on this site, the slant head is very thin in a couple of key areas already. I don't know if there's enough room to "move things around" enough to really make a difference big enough to justify it.

I'm not tryin to kill it, I'd love to see it. Problem is, I don't think anybody with a normal income could afford one. lol
