Exhaust mounting Delima

Got new header gaskets and fastners to replace crappy SS bolts that were too short and automatic "self loosening!"

Problem; to match the gasket/port opening, and make the bolts wrench accessable, I scooted the R/H header fwd about 3/16".

Now, to get a seal on the collector coupling, aft mounting tab has to be GROSSLY bent aft with a BFH (large darned hammer) and needing a longer fastner and looks like crap!

If I move the header back, I don't think I would miss the power, but would be unable to tighten 2 fastners AGAIN.

What am I missing, or what did I Jack Up? (that's my name and apparently my game).

?????????

I'm not quite sure what your doing. How do you move the header forwards? It only goes in one spot. Am I missing something here?

If the header is in the right place, everything should line up.

I know the small blocks have replaced two header bolts with a different style bolt to make it easier to get to.

You might just need a better tool.

Good luck
see ya in daytona.

Header Mounting Difficulty

Rick;

I'm not sure either. I can put the header on where the mounting tab will line up, but then two fastners on the right side are rubbing the pipe and I can't torque them. Last try, I took the thinnest wall box end wrench I can get that will put decent torque on the fastner, and slide the header against the wrench and the mount tab won't line up.

Then I pitched the damned thing in the corner and reinstalled the ugly-assed long pipes (The tapers on the extensions turned a motteled brown under the chrome).

See ya in Daytona. Just look for the red clutch Boss with ugly-ass long pipes.

Ride Safe!

Jack...I, also, am not sure what you are saying. I use stainless Allens for the header bolts which you can easily torque down using a ball end Allen wrench. I'm not sure I understand how you moved the headers up 3/16" since they can only sit in one place...Please explain again. If the header gaskets were not leaking you just should have replaced each bolt one at a time with a longer stainless Allen with a drop of anti-seize with no need to replace the gaskets. I think you shoud disassemble the whole thing, use a scalpel or razor to trim the part of the exhaust gasket that intrudes into the exhaust port, get 1/4" longer stainless Allens and get a new set of flanges for the collector to rear pipe connection.....Joe.
PS. Of course once you move the headers you also move the collector setup but I still don't see how you were able to move the headers???

Headers

My headers are probably unique, like a few other things on my scoot. The holes in the headers allow a good bit of fore and aft movement. The gaskets were blown (2 sets) due to not being able to torque the too short fastners, and the r/h one being slid so far aft, it's impossible to get a wrench on 2 of them at all.

I installed appropriate 1" fastners, and slid the r/h header just far enough forward to barely be able to put some torque on them with a really thin wall end wrench.

Guess I'm confusing myself, I'll see if MBHoss can help figure it out. I have cheap D port gaskets on it now, till I get this sorted out.

Thanks, sorry I cain't explain it better.

Ride Safe!

SUCCESS!

All;

Finally broke the code! Was not aware there is a left and right to my headers.

Swapped them side to side (never had the "wrap" on the aft tube for reference) and they FIT!

Straightened the aft pipe mounting tabs, and needed 1/4 inch shim in each side as it should be.

Thanks for all the pointers! If it don't fit next time (whatever), I'll resist Armying it (BFH), and try swapping sides.

Ride Safe!
