302 casting potential?

I was hoping I'd get your input in here, I've probably read your website 20 times today lol.

Do you feel these heads would work good on something like a 10:1 349 strkr? with either the stock intake valve or a 1.88 and with a 1.60 ex along with some mild port work? I realize that's a kinda vague description but I'm interested to hear your thoughts, thank you.
Now I know I've said my brother is doing a tight budget build but he got a free 68 318 so there's that forged crank or I'll give him a 360 crank and through some horse trading I can get the mains turned, remember people, you don't always have to spend money to get things done just keep in mind our old friend the barter system 8)
