Gasket Line Up?

Gasket Line Up?
Worse than ever. After original bolts striped, drilled out to thread 7/16 for the intake. Increased size of bolt hole in gasket. And we still are half a hole off. Note center line rib that should run thru middle of each hole. Lips seals torqued to about 5 pounds (seated).
Checked heads for height milled off, measure B on the chart is 62.5mm, and I am there, so the machine shop did not take off an extra 1/4 inch.
Two pix of current condition, and one pix of what I started with on the 3/8 bolts. Heads were torqued down without valley gasket being used as a template.
Thoughts?

Are both gaskets the same brand? Maybe time to try a different brand.
Good luck. I feel for ya.

Yep pressed down. When intake sits on it, a little better, but holes still blocked by gasket. Made one gasket hole egg shaped, and now this. Also appears I have about stripped out rear end (lip) seal bolt. So off to the store for that.
I'm thinking if I make the gasket holes elongated, on just one row of holes, the gasket will be too high. Viewing down hole thru the intake I can see gasket still blocking part of the hole unless enlarged. I am at the limit for the ridge of the gasket that surrounds the holes. Edge of gasket must be on machined surface, there is a limit to how far up it can ride in the valley. Plus the valve covers have to fit on after the intake is secured.
All gaskets Victor Reinz. It is almost like gasket is wider than it should be, or is designed if lip seals were not present. Pix show what happens if lined up on one side. Other side is way off. Or both sides are part off.
Family now on the warpath to get truck done. At this point I have lost all credibility with family and forum members and will have to burn my Rover man card.

I've never run into this. I think I'd loosen the end clamps, push down the center of the inlet gasket and screw in some manifold bolts enough to align the gasket, retighten the end clamps and see how it does. If it looks good, remove the manifold bolts and install the manifold and bolt it up.

Inserts are probably out, as we are now tapped for 7/16-14 NC, seems like the generic helicoils I had used a fine rather than coarse tap. But I'll see if they fit.
All this will have to wait until tomorrow, I'm off to the salt mine, get back at 1:30AM. Just like most guys, I only work half days, you select the first 12 or the second 12...
