Ok don't get me wrong, headers are great. But all I see is a pipe running over every single mounting bolt and spark plug. Is hooker still building a decent header? What's the flange thickness on them now? I cant say too much though cause there usually the first thing I do on my vehicles too. They obviously don't mess with your air care? I'm dreading the day they bring that up here.

I've heard aircare is on the way out, so you probably don't have to worry about it up there

These are replacing the same part# so fit is the same for me
No mods at all :smile:
Just put 'em on and break in the gaskets

There's lots of clearance to get at the bolts with a stubby wrench and a socket here and there, and even though they claim they don't fit angle-plug heads, they work fine on mine

My '78 truck is a heavy half and in 77-78 they eliminated emissions controls on these models for HP issues, so I have piles of room to pass and do so within recommended limits, even with a 355HP crate motor and a 795CFM Q-Jet

The flanges are 5/16" and the ports are raised
I've never had a leak ever from the first set, until they rotted away :wink:

When I install new gaskets on these, I torque down by feel, run the engine to temp and torque again, then go for a hard run, torque again, then torque a last time the next day after they have fully cooled off
After doing this, I've never had a header gasket leak, and I've replaced the gaskets twice on the first set of headers
I use Felpro 1406

I only wish I could have afforded ceramic this time around
These headers are $199 state-side, and $218 here
The ceramics are about $385 state-side, and about $525-50 here :twised:

Some pics of the new headers, and where they're going

That is a clean lookin compartment. Very nice. That a gm crate or you get it built?

Thank you. I'm very happy with it
It's a GMPP ZZ4 stock and it's pushing a 700R4 and 10bolt Posi
I blew the pinion gear out the bottom of the housing on a 12bolt 3:08, so I decided to upgrade for mileage and in-city power :wink:

I meant to send this to another member recently, so I'll post it here
My old 3:08 had about 200K on 'er and was acting sticky, so I matted it in the city ( to avoid a highway breakdown ) and it exploded during a 1-2 shift @ about 5500RPM with 405ftlbs and about 350HP

BANG !!!!!!!

I heard shrapnel hit parked cars and set off 2 alarms :mrgreen:
Funny thing is, it still rolled 'cause I only sheared the pinion gear shaft

Good ol' chevy power ...

Your lucky, If I want aftermarket sport headers, they are 1500.00 + state side for a Porsche, I put 200 cell high flow cats in 3 years ago, keep throwing check engine light, so I had to remap my ecu, which was $700.00, gave me another 20 or so more HP, and different rpm power range:) No more CEL

Checked my finances I'm broke. Divorce not even finalized. My fish need to quit bein freeloaders and get a damn job
