*Will buy a set of used 72 455 intake bolts if needed* I improvised with a longer manifold bolt with spacer so I could torque everything down and seal but would like to locate this intake manifold bolt if anyone has one (don’t haff to b purrtee if’n it threads she is nice ; ) My knife tip is pointing at one MIA. It is longer than the recessed pocket bolts. For quick id the manifold bolts have a recessed bolt head center versus cylinder head bolts. Tried my 430 motor bolts but different than the 72 . Unless someone is sure the one they have is correct I will back it out and measure it (getting ready to rain now). Thanks for any help. Regards, Fritzentorquin!!! : P
