Our 455 intake manifold was bolted down with 12 bolts - 9 long and 3 short ones. Also, the bolt heads had different markings - a few were grade 8 and some were grade 5.
Should all the bolts be the same length, or are 3 of them short because of the thickness of the manifold at those points? And if I replace all of the bolts with new, is grade 5 ok?
Thanks,
John
