need help with big block heads

[newschool]

Thanks for all the help - this is my first big block to build and I'm finding out that they are alot more expensive and harder to find parts for around here (West TN). Is it true that I'll need a 119cc combustion chamber since I am running the 11:1 dome top pistons - to have enough clearance so the valves and pistons don't hit? Which BB heads were better - the oval or the rectangle ports? I really appreciate everyones help - I'm trying to get a grasp on all the BB Head info. I would love to buy a new set of aluminum heads - but I have a baby due in Feb and a couple other car projects going, so I'm tryin to watch my funds, especially since this is not a car I'm going to sell.
