360 with B&M 10239 scalloped flexplate. externally balanced assy. I wanted as much TC into the trans rearward engagement as possible so I have these (4) button head bolts that weigh 8 grams each & the nuts to take up that distance from the back side of the plate to the (4) TC flat pads & the nuts weigh 3 grams each. the OE bolt weighs 9 grams each. will this cause a balance issue? thank you for your time.
