65 400 intake and exhaust manifold bolts question

Hey everyone, my 65 400 engine is going back together...machine work is done...crank and flywheel are getting balanced...I'm looking for intake and exhaust manifold bolts. Can I use grade 5 or 8 bolts or do I have to find a set of originals...any advice would be great thx
