Anyone out there who can give input on this? My exhaust manifold is cracked and I'm wondering if going to a header is worth it or not.

Id like to find a header that fits the 4.2!

IMHO I don't think there would be any adverse problems going that route but if you have an O2 sensor in the manifold you may want to make sure the new header has that provision. I'd like to install one if I can find a suitable header

pacesetter and borla make a header for the 4.2. be sure to get one for the 87 and up 4.2, the earlier headers are different.
