Time for some tunnel ram tuning !!! With that in mind Ive had my carbs apart twice, once to find out what the hell was in in and another to change the power valve. And these gaskets probably won't hold up and will tear the next time. There are a few brands out there but what have you had good luck with, $ is not a issue for these parts, same goes for valve cover gaskets. Summit seems to sell the rubber style that has a full steel construction for valve cover gaskets ? Thanks !
