Tube headers

I got my Cliffords about 13 years ago. No problems and still going strong.
It it my understanding that they have had some outsourcing problems and it has been rumored that they have a very reputable manufacturer making them now. I have no confirmation on this. All companies have problems now and again. On the intake side,compairing Clifford to Offy, I have had porosity problems with a Offy. Minor complaint that powder coating took care of.
The old Mopar Performance 6 into 0ne headers took alot of reworking to get to seal but now work fine. I guess that our fondness for that six on the lean makes our hobby a little harder. But it won't make me go to a belly button small block chevy none too soon.
