what is a j40 head?

big g · 12-26-2007, 07:02 AM

I recently purchased a 1985 dodge 1ton crew cab with a 360. The guy I got it from said he replaced the original heads with a set of j40 heads. I want to get some headers for it and wondering if they will fit if I ask for headers for a 360 or are they a different size for a j40 head. Thanks

the only thing poping in my head right now is from a toyota which makes no sense. i'll do some digging for you.

coming up empty, can you grab a casting number off the head?
