Crate headers?

[Canadian]

Can you run the same headers on a 602 and 604?
Don't see anything saying no....
And if NO why?
Thanks

bolt holes in a 604 head is not centered like in a 602, 602 can run stock location headers, you can run stock location headers on a 604 but it won't line up the exhaust port causing a restriction.
