Re: 0630 vs 0331

So can anyone provide any guidance as to whether an originally 0331 equipped engine retrofitted with a 0630 head would have issues passing emmisions?

Is the difference signifigant or would a otherwise healthy engine pass the 2001 emmisions standards even with the "dirtier" 0630 head?

I'm not needing a head swap yet... but if it comes to pass I'll try to squeak past emmisions with the 0630 head.

(we don't have visual of that "depth" - cat installed? yes, continue)
