I have twelve original intake bolts, 'A' headmarks. Below the flange on the shank there is 1/4" area that is unthreaded. I have some other original bolts that are exactly like the 'A' bolts but have 'M' headmarks and are threaded all the way to the flange. Are these also intake manifold bolts or exhaust manifold bolts? Or both?
