ok the standard firing order of a sbc is 1, 8, 4, 3, 6, 5, 7 , 2.

The ones that are 180 degrees apart are 1-6, 8-5, 4-7, and 3-2.

in a 4-7 swap and or a 3-2 swap, do the cylinders that are 180 degrees apart still the same as the standard firing order? it looks like it to me.

I am getting a set of headers and this is kind of a big deal seeing that I am spending 1300 on the set... stahl btw.

Help would be great.:thumbup:
