When do you replace valve springs?

Since engine is disassembled will replacing the springs with APE performance springs require new valves or other adjustments?

Also looking for a base gasket recommendation?

Very rarely. Why do you want to replace them ?
Generally it's done if they are broken or have gone below service limits or you are doing something with a different cam.
Base gasket oem Suzuki. Aftermarket are available but not worth the risk for the price difference.

The 750 valve springs are the same as used on the larger 1100 and 1150 engines, which use larger/heavier valves. Unless you are going to run high lift cams you should leave the stock springs in there. The 2nd generation 750 has oiling system issues which destroy cams and rockers also, so the last thing you want to do is increase contact loads on the various parts.
