I'm using Hedman's on the 52, coated, I'm going to put the "special " bolts & loks on them as I've blown one gasket so far, on a "hard accl. run" & 6 grand plus shifts!!!
Before the members go off on a 3 page rant over painted headers
On a car that never sees bad weather, the black steel headers on my old Strato Chief were installed in 1991 and are probably still like new They were in 2010 .
Got a set of Black Jack "ceramicoat" headers that have been on the 'Beau since the mid '80's too small realy for the 496 but they just don't want to DIE !
For $50 more for ceramic, why would anyone buy the cheapest painted headers? I mean...the painted ones will rust pretty much within three months unless you live in death valley.
I had painted headers on 3 cars before, and they suck. I had a painted 4 into one header on a bike once... Super Sucked. My lawnmower exhaust sucked as well!
It should be noted that the Summit headers I have appeared to be coated on the INSIDE as well, really, no BS!
$250 Dollars plus FedEx... it's a no brainer for a simple setup.
Now, (yes a big NOW) as to how they flow compared to Hookers or Doug's Tri-Y or whatever, that probably is another story.
As I stated before, buy some good gaskets! The cardboard these Asian headers come with are completely useless (just for a packaging show). Also, Buy some good bolts!
If I was to do it again... I'd probably buy these Hooker Stainless, as they've really come down in price over the last 3 years. But question is, will they fit the power steer 65-70?
So if you're not going for a Engine Masters shootout winner, the cheapies will work better than just fine.
Cheers, Mark

About blown gaskets, I'm told if you use flexible pipe at the collector, you reduce the chances of blowing gaskets, and the locking bolts are a waste of money. Theory being there will be less stress when the engine flexes under hard accelleration.

Big horsepower will flex more
Street motors with good quality gaskets are fine
my pontiac had 19 year old gaskets and didn't leak and more Hp than you are quoting
The lok bolts I just ordered are a allen head with a "serrated" head & a groove in head of bolt. There is a "oblong" washer that has the "serrations on the inside of hole & locks onto the head of bolt & jambs up agains hedder tube. Cire clip goes into groove to hold the washer on. NO WAY can the bolt back off. I just re tightened the hedders "again" & YEP they were loose!!! Shipped bolts to W.Virginia for my June trip to car show so hope I don't blow out another gasket but do have a spare from last time down there!! Maybe take it easy on the POWER shifts?? NAW, thats a BLAST!!!!

I used the Stage 8 bolts on mine as well Pete, but haven't put the locking tabs on yet. I checked all the bolts for tightness, and they were still as tight as they went in.
Perhaps the Earls graphite gasket makes the difference?
