Read the rule several times. Says I can block on intake side of head. The rest of rules in head section and in intake section does not address plugging crossover in intake passage. I'm asking as I used lead to plug intake side on head. Pulled intake today because of having it be so hot along with carb and losing .2 ET. and found all the lead is gone from head. Yes it's gone with exception of a small nugget.
Want to plug at intake as I have no intention of pulling heads off.
I can make a plate to cover holes at intake surface, but dont know if its enough.
