Just read a post by a fellow having trouble putting the valve adjusting covers back on his Champion after replacing the gaskets. The best way is to stuff the holes full of shop rags (to keep crud out) and scrape the surfaces on the engine and the plates well. When you pull the rags out, hopefully all the little bits of gasket go with them but check well to be sure. Cut 2 threaded rods about 1/2" longer than the bolts. Cut a notch in one end to accomodate a screwdriver bit. Put gasket on cover plate using 'Hi- Tack' gasket compound; don't put anything on the engine side. Put you temporary studs into the bolt holes in the block. and then slide plate into place over the studs. Put a nut on each stud and snug it up. This should hold it in place so you can remove the stud and replace it with the correct bolt. (Engineers must have burned the midnight oil dreaming up ways to make such a little motor in a large space so exasperating to work on!)

Perfect! Thank you. I came up with the same idea about making up a couple of bolts to serve as a guide for the cover bolts. Trouble is, I still couldn't get the covers in, so I went to the trouble of removing the manifold which will give me more working space to put the covers back on. Someone did enlighten me regarding the two sheet metal splash guards in the two valve chests that the company must have added late in the production of these engines to reduce oil leakage from around the covers. I did remember not to put sealant against the engine side. As far as removing the old cork, I took out the covers and ran a rotary wire brush around the gasket surface to remove all traces of the old gasket before installing the new ones. I'll be happy to get this job over with . Again, thanks. Tony-
The Baffle Plates are NOT to help with Gasket leakage, but to prevent burning Oil by sucking it in the Intake valve stem due to the splash from the Valve Lifters, which get looser as the mileage builds and the lifter bores wear !
However, plugging the Valve Lifter Oil Passage holes under the lower part of the gaskets, WILL reduce leakage a Lot.
These holes have Oil Pressure !

So I could leave the baffle plates off then! My car doesn't have over 40K miles and I don't expect to be putting that many miles on the car and the plates are tricky to put back and still be able to put in the cover bolts. TonyComment

CERTAINLY NOT ! You keep mixing up the Two issues with each other.
The Valve Lifter Baffle Plates were on all 169 engines from near the beginning, if not forever for a good reason, the amount they are needed just increases with Mileage, but they always work to help not Burning as much Oil.
The Valve Lifter "Lead Carburetor Plug" Kit was a Service Letter aftermarket fix for seriously leaking Valve door Gaskets due to open Pressurized holes, 12 of them! These were not on that many engines at all.
