Gentlemen I've been sitting here agonizing over my chronic exhaust leaks and I think I see the problem, take a look at this picture, don't it look like the Hooker header ports don't match the location of the ports on the L31 Vortec cylinder head?

this is the passenger side head, can you see the black square outlines and how they are all shifted over to the right about 3/16ths of an inch, all four ports are like that, as if the header was bolted up a bit too much forward and not on center of the exhaust ports

am I crazy or do you see it?

the driver side is offset too but in this case it seems like this header sits about 1/8th of an inch too far back and needs to slide forward a bit for the holes to align

I don't think I can fix this by welding the bolt holes up and then re drilling them in their proper locations as it's a poor design and the holes will hit the pipes

Remember this post Gregski?

I think I'd widen the contact area with a MIG or TIG or even my Oxy Mapp torch then file or grind or mill for flat contact.

did I mention the wife will be out of town this weekend and I have already scheduled the next Dyno Test for Tuesday October 4th the year of our Lord 2016 so I am making a list of touch ups WE need to make to make Rusty Roller Ready

1. Fix Exhaust Leak (AGAIN)

2. Replace Magnaflow mufflers with just large resonators

3. Shorten #5 spark plug wire

4. Fix/calibrate one of the AFR Oxygen Sensors

5. Eliminate transmission noise by draining a bit of fluid

6. Finish hooking up license plate light

7. Maybe try a 1" carb spacer

8. something I forget

9. misc.

10. etc.

I'm excited to see the dyno results. There are none near me and being without a trailer to take my truck kind of leaves me hung out to dry.

Not enough bark with the Magnaflows?

Then you might as well rig up the spark plug flame throwers while you're at it. I would suggest relocating the exhaust exits though. No fun when you realize that the burning smell is in fact...you. :D

and the other side, sorry some pics were taken with the header upside down

then I decided to cut up the flange into three separate pieces, this is an old Hot Rodder trick passed on from generation to generation by the spinning angle grinder

so first we mark the flange with a Sharpie with surgical precision, ha ha

a final look at the finished product - the passenger side Hooker header be modified

then I got bored of all the grinding and decided to get rid of the Old Man Magnaflow mufflers - they just had no bite and you know Rusty needs a proper Soundtrack

laying around we had our 9 inch resonators, a bit too small but it would be criminal not to give them a go

mandatory stare and compare old vs new(ish)

I give you Exhaust 6.0

Welded by the light of the moon, (no seriously I welded this up in the dark, from spare tubes, not bad at all if I do say so myself)

Which gaskets are you going to use with 6.0?

Exhaust not 6.0L ;)

wait what? that's not an LS under my hood? ha ha

I hope to git these round port aluminum Mr. Casket ones Part # 7402G (G is for custom made for Greg I think) which I already owned once, but like a fool returned

Wide Open 10-01-2016 11:04 AM

Re: Restoring Rusty
 
Yeah I saw those and wondered if you were going to use them or those never have to retorque ones.
