While they don't need to withstand the stresses of a head bolt, make sure the stainless bolts are hard enough and that the heads won't twist off (shear). I have used stainless screws and marveled at how frequently they broke when I was screwing them into wood, fiberglass or any other hole that wasn't too small. It may be better to use the tri-plated bolts with anti-seize.
They didn't use stainless, just steel.
