12, 15 and 18 degree take the same intake
700 HP is easy with either 23 degree or 18 degree
I respectfully disagree, it's not easy to make 700 HP with 23* heads without spending a ton of money. (why don't you tell us how much you get for a 23* head motor making 700 HP guarenteed/dyno'ed. without additaves/nitrous) Exceptionly/good 23* heads flow maybe 340 CFM. Good 18* heads flow 400 CFM plus, with a 434" it's possible to make 800HP plus with 18* heads for less than $10,000.00 without additaves,
Carb to pan.

Here is our 427, 759 HP

I will agree 18 degree will make more power, but unless you plan on buying used parts, $10,000 is a tight budget carb to pan.
Just saying 23 degree heads can make 700 plus horsepower.
