/6 with headers???

I've been using Clifford's /6 headers for 5 years now...2 years with the super six, and now on my rebuilt 225 w/a 390 Holley 4-BBL. No trouble whatsoever...I love the look, sound...Everything...It really wakes these slants up...Especially on the strip! Ran some 18s with the tired slant and the super six...Now running low 17s shifting @ 5000. It would go faster, but I still have my 2.73 gears in the back :/

To answer your questions...I haven't had any problems on cold days (I live in WA. State)...It seems to me like I maybe have to warm up the car a tad longer than before (I usually prefer to get it up to temp. anyways). Being that I bracket race my car a whole lot, I'm extremely happy with these headers.

My only complaint is that they come from Clifford coated in a black finish that didn't look or last all that great. For about $90 I had them powdercoated chrome.
