Default Attn BBC experts! Need Head Gskt Advice.

I'm currently putting together a bogger motor for my friend Justin, and we've got a pretty well built big block that should be making somewhere in the range of 500 horsepower. I want to make sure this thing gets cooled as best I can, and I'm seeing a lot of differences between the gaskets I have, the other ones that are available, and what this block looks like.


These are basicly the same heads we're using, same coolant ports.




This is the actual block. Stock bores.





And then, these are the gaskets we have.



These are the ones I believe we need.







It was apart when we got this, so we dont have original gaskets. As far as I can tell, it used to have these



- judging by the little bit of corrosion from the open gasket ports on the front of the head surface. Not to mention we have only one larger lower port, while the gasket has none. Am I right with my assumption that we need these instead?

I'm also wondering why the holes in the gaskets are so small for deck cooling ports along the top?

I just want to make sure we wont have cooling issues, so if anyone could point me in the right direction and maybe even give me some tips for better cooling, I'd appreciated it.

You need the ones in the second picture. I made that mistake when I put my motor together.
