Yes I know this has been betten to death, I searched this site for hours last night about header issues. I just purchased this old 240z drag car as a roller. This car is was so poorly put together, baleing wire and twisted wires with duct tape everywhere. I stripped everythingout and started over rom scratch......
Anyway I drop in my 406 roller motor and find out the the old block hugger headers that came with the car dont fit my RHS angle plug heads. So my search starts for the best header that will fit my heads. The real problem is that all the engine mounts are home made. So most of the post on this subject are a couple years old..... What are the known headers that fit aftermarket (RHS) angle plug, d- shape?
I came up with #DAT-402C as being the best but still not sure if thats the latest, greatest set......
Thanks!
