the 5/16-18 header bolts arent the easiest thing to find in 1"...I actually have regular stainless bolts holding mine on right now and have no leaks... I plan on switching to header bolts but I'm still waiting for all the leaks everyone told me id get by using the gaskets that came with my headers...so far no leaks at all...(I did use the Indian head stuff between the gasket and header to help seal things up though.)

I'm impressed at how much the eastwood internal header coating spray keeps the temps down... mine have been on for about 200 miles now and havent really changed color at all (stainless)

You may want to sand those pacesetters down and put some high temp paint on them...the paint is just for shipping/ storage purposes and burns off in a week and they rust out... thats what I just replaced..
