I went to Kragen and the lady told me that they only had "GSR" spark plugs, so i got them. They work fine, but I want to know if I shouldnt be using them.
They are fine. Just gap them to your specs.
If you're talking about the spark plug wires, they won't fit right. They will work, but they leave about an inch space between the valve cover and the top of the grommet seal (basically water can just go right in there).

I mean the actual plugs themselves, because if they really had to have a separate entry for Gsr and Ls, then they must be different somehow (cant really see how though)

B-series non-VTEC plugs are just a little longer and extend into the combustion chamber just a tad farther than DOHC VTEC plugs. I'm not sure what effect it could be of having a shorter plug in there, possibly not as complete combustion as it would be with the correct plugs?
I put in some toyota celica gts plugs in my gsr. Mine were bad so I bought some new ones for my gf ...found out her stock was denso iridium so i put those in mine and gave her the new ngk's...I measure there gap and its perfect to gsr...length wise also....runs fine to me....

You might want to check the part numbers... they might use the same type of plug, but the heat ranges might be different.

That's why the electrode ends up closer to the piston with LS plugs. They are "warmer". If you compare the same plug with different heat ranges you'll find that overall the colder plug is shorter.

GSR on the left.
The GSR tip is longer, but the insulator is shorter.
I ran the GSR plug in my LS engine for quite some time. </TD></TR></TABLE>
Are you sure the left plug is for a GS-R? Where did that part number come from? Is ZFR5F-11 a platinum plug, or copper, or something else? I've always run BKR6E-11's (copper) in my GS-R.
