GAMESS own documentation 
(http://www.spec.org/hpc96/docs/RelatedPublications/gamess/re
fs.html is one version online) has the citations which give 
the integral procedures in detail, from which you should be 
able to figure out all you need.  The computational cost of 
SCF procedures is one of the most thoroughly studied aspects 
of quantum chemistry and understanding the computational 
cost of these procedures is far from intractible if you are 
willing to read a few papers.

After checking out the GAMESS-related literature you might 
check out

International Journal of Quantum Chemistry
Volume 40, Issue 6 , Pages 753 - 772
The prism algorithm for two-electron integrals 
Peter M. W. Gill, John A. Pople 

as one of but many papers on the subject which detail 
integral algorithms and their cost.
