Default guide lines for porting LS1 heads

any one knows the correct guidelines for porting the LS1 heads? i mean where to port and where to leave the port untouched. i got guidelines for porting LT1 heads and i wonder if the LS1 heads are the same.

No, not the same, and it also depends on which casting of LS1's you port.
