Guys with ZZ4's and headers HELP

[dkooi]

I have a ZZ4 that I'm going to be putting in my 72 (2wd automatic ) soon, and need some advice on the kind of headers to run. The heads have D-shaped exhaust ports, as well as angled spark plugs. So it's my understanding that your everyday header isn't going to work. I've found block hugger style headers that work with these heads, but am concerned about clearing the crossmember on these trucks. Anybody running a zz4 with headers?
