D port heads usually have the exhaust port raised. Just make a paper template of your header ports noting the location of the bolt holes. lay the paper over your head, matching up the bolt holes, and see if it fits.
ok guys I recieved the headers in the mail yesterday and came with gaskets, so I put the gaskets up to the head ports and they cover them, its close at the top, but the bottom is fine. The bottoms overlap over the whole a little bit but not much. so am i okAY?
