Restrictor plates

Any input ? Sbc, flat top piston, 10/1 550 hp, 750 hp carb 1 power valve, vic jr, runs 11.0o.we have run this combination for 5 years with out issue, we tryed using a restrictor plate to race index and the one time we did it worked however after the 5th pass we lost a head gasket and after the tear down found # 8 piston was missing a 1/2 x1/4 inch piece off the outer edge, no other damage. Most of the plate people ive talked to said it has nothing to do with the plate ! But its strange that it never happend before and its been 2 years since that happend, and we race almost every week. Dont want to lose a motor ? Any thoughts
