My dad just installed these on his 70 c10 with a 350 and they fit good with no probs. He's happy with them and they were cheap.

I was also wondering how good these headers hold up you sure cant beat the price.

HotRod929 · 08-27-2002, 12:11 PM

Yea that was going to be my other question. Will they hold a good seal with the gaskets?

70c10 · 08-27-2002, 04:13 PM

So far so good. Had pretty thick flanges.

stllookn · 08-27-2002, 05:18 PM

How low are they below the frame...can you still lower the truck? How about clearance on the starter? Did you have to put a heat shield on it? Hey...got pics?

HotRod929 · 08-27-2002, 06:13 PM

Yea pics would be really helpful

1 1/2 into 3 is a little odd. Lots of the guys here use the Hooker Comps. There a 1 5/8 into a 2 1/2 collector. I run em and there great. The Hookers are thicker wall tube also.

I have the same headers on my truck. I have had them for 2 years with no problem sealing. I did the old drag racing trick of cutting between the primary tubes.
