I was thinking the same thing. I have a feeling the seat failed just before I parked it last to repair the coolant leaks. So, the running theme here seems to point me towards either new heads or a new engine. I was just gonna take my current ones and have a shop replace all the seats, but I don't think y'all would agree.
My intent with the car is to have it as a daily driver with some added HP for a little get-up-and-go when I wanna get-up-and-go. I won't be taking it to the track or anything, just a grocery getter that goes fast. Initially, my plan was to add headers (done), upgrade the intake, carb, and air cleaner, and pretty much call it good. But that was just a beginner's plan...
