Sorry.. I was in a hurry. it a 440 ..and it has the 906 heads.. And used ARP studs. I should have explained it better. I forgot they used to put studs in for exhaust manifolds and head too. the studs are sticking out past the nuts about 1/4 inch. If I cut the stud off.. I will be able to get the flange against the head. But when I go to use the gasket.. And then The nuts are going to be to tall. Thanks again for your help.
