mac headers

i got some Mr. Gasket headers bolts....3/8-16 x 3/4 im pretty sure that is the size i need.

Those will work.

Personally I will never buy anything but locking header bolts from now on. I went through more header gaskets on my 88 with regular non locking bolts. The $55 for a set of stage 8 locking header bolts is worth it.

hmm well ill see how these work if that happens ill invest in a set.
 
I like using Allen head socket bolts on headers. Put some locktite on them also. This will help keep them tight. For some reason aftermarket headers like to loose the bolts.
 
I get them from work. Stainless steel bolts is all we use we always have them setting around.
