I got some short valve covers. You'll just have to wait and see what kind
Don’t think those will work. They’re center bolt valve covers.
I think Martin meant LT-1, not LT1?
I meant LT1. That was the RPO, there was no hyphen in the RPO. That was just the badge on the Corvette. They didn’t even call it an LT1 in a ‘70-‘72 Z28.
Z/28 was a badge, Z28 was an RPO.

Makes sense
I should know better than to try and correct Martin lol
Welp, I made a goof. I may have dropped a washer into the engine.
I wanted to freshen up the exposed head and block surfaces so my new intake looks nice.
First primer, then paint.
Thing of it is, the paint dribbled down onto the sealing surface of the heads.
So I put the intake gaskets on dry, held in place gently with 2 bolts, and traced around them with a razor blade. When I removed the rear bolt on the passenger side, the washer fell off the bolt and I heard it clink onto what sounded like metal. Definitely not the concrete floor.
And now I can't find the washer. I'm using a flashlight and long flexible grabber tool. Can't see it on the bellhousing, trans, or frame.
Do I need to drop the oil pan and look inside the block? It may have fallen into the distributor hole, a coolant passage, or into the head.
Or can I just get a magnet drain plug and hope for the best?
Or should I get a Harbor Freight borescope and do some internal research?

If it’s a washer for the intake bolt it’s too big to go through the screen on the oil pump pickup. If it made it down to the oil pan it’s not going anywhere. One problem is a washer that size isn’t going out the drain hole in the oil pan.
The only way to get it out is drop the pan. Or if you know it’s down there and don’t want to drop the pan get a big rare earth magnet and stick it to the bottom of the pan. It really won’t go anywhere then.

Did it bounce off the exhaust and go for a ride? Small stuff goes a long ways when it bounces off something on the way to the floor.
That's good advice about the magnet. I probably spent way too long looking for it, but my son joined me for a while, which was really fun.
Didn't find anything with my new borescope though.
Slapped 'er on snug.

Fasteners always find the darnedest places to fall into.
Running?

Just about ready to fire. Need to finish routing a few more vacuum lines and figure out the breather situation. My new chrome valve covers have a larger diameter hole than my stock ones, so the breather pipe that connects to the air filter housing is too small to fit into the valve cover.
I have a round push-in style breather but it hits my EGR valve because of the edelbrock egr adapter. I'm running the egr adapter so the egr will clear the valve covers.

Let there be power.
I don't know if the unsteady vacuum is normal, but it has a weird clunk or miss every so often. Any idea what that noise is?

Does it sound like it’s coming from engine or bell housing/trans area? Seemed louder underneath to me. Could be throw out bearing maybe. Does the noise change when you push in clutch or rev engine?
I thought about it some more and tightened all the exhaust manifold bolts and exhaust downpipe bolts. 3 bolts were able to be snugged down, which eliminated the intermittent clunk noise.
But I still can't figure out why it's missing. I pulled each of the spark plugs off one by one to see which cylinder might be causing the miss, but that didn't confirm a specific one.
Anyway, I installed this old tach I had laying around. So I got that going for me, which is nice.
