427 SB Mopar build

is the 360-1 heads the best for bigger cubic inch strokers? without going to w8/w9, which other head will support 700 hp?

i'm hoping my w2's will support 640 hp and i might want to take it to the next level, 700+ hp.

You'll spend more money going W8-W9 because of the custom/expensive parts needed to go with them like rocker gear, headers, intake, port work.
It all depends on the amount of power you want, and how much you are willing to spend.

I hear guys say just go BB because they are cheaper to get that kind of power from...well maybe but not by much!
