Perhaps this will pep up the '90.

But, in order to help reduce the valovetrain friction I have actually thought about using the 93-95 Vin L heads with the Roller bearings instead of the Pivots... Don't think it would be a great diffrence, But something I would like to do...

My 91 has the Maxifuse Relay center, all the same suspension components as a 92 Bonneville( Springs, struts and the like )... And as were were doing some research we found that the 91 Vin C and 91 Vin L actually used the exact same cam with the exact same setup... I was kind of shocked... My car is a 1991 Model with a Build date of October 1990, So my car was most likely one of the earliest 91 models made..

But as for the suspension, hmmmm: I wonder about the SSE. The LE may have had '92 suspension, but hmmm...

Now, to see how it works for me.
With the intake off.
With the C gasket over the L gasket.

The PCV hole is .775". The closest expansion plug I found was 3/4", which was too small, so I tried RTVing it in. I found some Expand-tite repair 3/4-7/8" rubber plugs at the parts store today, back to the garage to see if that will work - not sure, because the hole wall is wider toward the end of the head, and there'* a pushrod right behind the hole.

The C engine is out. Found this during the process:
Imagine the part the light is shining trhough going all the way around. Apparently that was the knocking noise. But, would that cause it to stop running? The trigger is part of the hub, not the pulley.
It looks like all of the C brackets will move over to the L engine. The Expand-tite may or may not work - sticks out a lot. One of the expansion plugs popped out after curing overnight, so I either need to re-apply, or try to get the rubber piece to work.

Stupid question here.... Do they make a shallow freeze plug in that size... Or is that hole a jagged hole?
