Removing the headers from my '79 T/A...... Going back to iron logs.

Engine is a '76 Pontiac 350.
The engine code is: XR 0300605 with 6X heads.

The exhaust manifolds are:
LH 499624D dated Feb. 25 '77
RH 496002A dated Jan. 20 '77

I have no real good idea what size manifold bolts I need!!!!!!

I have a service manual on CD....... A real pain in the butt to navigate, by the way.
So far, I've found a reference to several sizes..... section 3.275 shows:
1.05 3/8" 16x1 3/4 (what the heck does the 1.05 stand for?)
........... also 3/8" 16x2.70 for the LH.

I can deduce the 3/8" head size.... the 16x1.75 thread and length stuff.....

But HOW MANY OF EACH..... AND WHERE DO THE DIFFERENT SIZED ONES GO??????

I think I remember hearing stories of some folks busting into water jackets or something when torqueing down an exhaust bolt that was too long. Anyone help?

This is no concours restoration but I do want a trouble-free, long-lasting install. Love the performance of the headers but hate the leaks. The Pontiac heads have got to be the hardest things to get headers on correctly. Here's some pics of the car...... http://www.cardomain.com/ride/2678545
