Hey guys if you read my sig i have a set of hedman elite longtube headers. They are on backorder right now, but i called hedman cause i ordered them in may and am kind of distressed with the wait. The guy said to cancel my order. He said that they will not work with aftermarket heads. And that they are made for stock heads. I plan on putting on afr 185's and i heard those have stock locations for exhaust ports and etc... Can you guys shed some light on this being the real masters on this issue. Anybody with experience that knows if a header fits on stock head than it fits on afr's or vic jr.'s (i don't know for sure which one, just going with which one i find a better deal on, i am leaning more towards the afr's though)???? Thanks in advance guys.
