Reply to "Headers"

When re-installing the original headers on the original motor, my headers didn't fit right, so it was a two man job getting them in and took quite a while longer than anticipated. Of course, afterward, I learn there is a tool available called a Header Spreader Tool. It looks like the round drum brake spreader on drum brake systems, at the bottom. In fact, that little device which has the wheel in the middle for adjusting drum brakes through the slot on the outside of the brake backing plate has been called "The Poor Man's Header Spreader". Place it between the header pipes and screw it to push the header tubes apart to line them up to the exhaust port threaded holes, and Waa-La!
Also, I ended up with several sets of exhaust gaskets that didn't fit quite right and one of which was very thin on the same exhaust port that failed and burned through on the original header gaskets. I used Mr. Gasket exhaust gaskets and a friend put them on the headers before installation, inserted the bolts from the backwards direction to hold the gasket in place on the headers and got out the old Dremel Moto-Tool to match and widen out the gaskets to match the tube diameters of the Headers.
Gonna have to return some parts if I can find the receipts.
This is not the answer to your original question, but this is a bridge that's gonna have to be crossed.
