if the header flange is strait and flat and your useing a decent header gasket youll rarely have problems with any material,(personally I prefer the copper ones) AND THE USE OF socket head cap screws with a coat of anti-seize paste on the threads are a common practice and if youve coated the bolt threads in the heads with ANTI-SEIZE like you should have, almost any decent 6"-8" box end wrench can be used to snug the bolts up firmly.
but at times youll want those header bolts or socket head capscrew bolts
due to clearance or tool access issues.

YES! its very common to find you need to drill out ALL the bolt holes a bit larger in the less expensive header brands , and even some of the high end brands at times ,simply because the heat of welding tends to warp the flange just a bit distorting the flange, its no big thing in most cases you simply find and use the next larger drill size and a quick clean-up pass thru each hole does the trick, youll also find that the use of studs or cap screw bolts, and copper header gaskets tends to make the job easier

I would strongly suggest BOTH stainless bolts and the use of ANTI SEIZE on the threads
