I broke a valve back in 2022 on cylinder 7. It has Manley valves and upgraded springs unsure about the brand but undamaged. Took the head replaced the valve and ran perfect until today. Broke cylinder number 8 this time. Both were the exhaust valves too. First time around I was thinking bad luck but to happen again on the same head there has to be something I’m missing. It’s Lito tuned forged internals Vortech supercharger pushing out 18psi. Any help would be appreciated and apologies if this has been mentioned before I tired using the search bar with no luck.
