Default Bore and stroke sizes in relation to c.i. on LS1

I know someone has probably done a chart for this or posted the equation, but can anyone help me out?
I searched for it but came up short.
Any help appreciated.
Also, am I right in assuming that the best flowing non C5R head appears to be LS6 stage III heads?

Yes, but skill between head porters does of course vary.

Thanks for the responses guys.
Absolutely Colonel.
I'm assuming in that chart, he put the names of those vendors just as a reference and that there are others who will make those same size cranks?
I was pretty sure Scat, and LAE make them as well for LS1's.
Anyway, the chart was what I needed, thanks.

Its sorta old, and those were the popular cranks at the time. I think SCAT will cut one with about any stroke (within reason) that you want.

Go here, its an Excel spreadsheet that a member (not sure if he wants his real name mentioned in public, and I forgot his screen name <img border="0" title="" alt="[Embarrassed]" src="gr_emb.gif" /> ) built.
