ok i will be buying the edelbrock t.e.s. headers for my truck but before i order them i have a couple of questions. 1. What lenth header bolts do i need? i'm going to try and use the new style that breslin makes. the one with the little allen head screw in the middle to make that locking. but they offer them in both 3\4 and 1 in long and i dont know which i need. 2. what kind of gaskets do i need square port or round port? maybe that is a dumb question but i have no clue so any help would be nice. also any suggestion on brand of gasket so i dont buy something that sucks and have it blow?
