I just bought some headers for my 250 from ftyler. Now to install them. I have read somewhere that you should replace the alignment pins that are in the front and back of the head with actual bolts or studs.

Is this necessary to get a good seal?

What is the process and recommended bolt/stud?

Thanks!
